- When the battery runs out, it’s nerve-racking, but unfortunately, it happens. The more functions our devices provide, the more power they need, and they’re hungrier than hungry hippos at this point! That’s why charging technology is all the rage now, and the new big thing is wireless charging.
Even though we’re just now seeing this technology take off, the basics of how it works were discovered not long after we started to understand what electricity is. Near the end of the 19th century, engineering mastermind Nikola Tesla showed that two powerful magnetic fields can slightly transfer energy between their sources when they interfere with each other. This trick found its use more than a hundred years later!

SUMMARY:
- Every object with enough power is a potential source of an electromagnetic field.
- Magnetism and electricity are two sides of one coin. When electricity flows, it creates an electromagnetic field.
- To make a strong electromagnetic field with copper wire, you need a lot of it. Still, it’s one of the most fitting materials.
- The biggest surprise here is that the technology behind wireless charging hasn’t drastically changed since Tesla.
- The main problem engineers struggled with for a long time is that coils weren’t effective. The power of the field depends on the number of coils you can fit in the device.
- Another problem is that electromagnetic fields need to be close to each other to keep a strong connection.
- That’s why wireless chargers today come in the form of mats - you need to put your phone right on it to get any juice at all.
- This new tech isn't huge yet because let’s face it - wires are still faster than an electromagnetic field.
- Wireless charging takes around double the time to charge a smartphone from 0% to 100%.
- There’s no way a short-range electromagnetic field can cause any harm to you.
- As you can imagine, the whole method of electromagnetic charging won’t stay the same. As with anything, it’ll only get better in the upcoming years.
- Resonance charging will be good for devices with a high level of power usage, like cars, laptops, or even some robots.
- Another idea researchers are considering is laser charging. It may be extremely powerful and focused, but it has big bugs to work out first.
- A laser will work on any distance but needs a clear line of sight to the device. If interrupted, it won't work at all.
- Some other fresh research is aimed at the use of infrared light-waves, radio signals, or even ultrasound waves to charge phones and other devices.

If you could charge your phone with sound, what sound would you choose? :)
Painkiller (Judas Priest)
Farting ! 😉🤣
Sound of Thunder ⚡ would be Cool 😎
Wind, there is a lot of it outside
my audio sucks

Bright Side: copper is an unbeatable conductor of electricity
Also Bright Side in another video (why graphene will take over the world): graphene carries electricity more quickly, more precisely, and more efficiently than any other known material.
Haha
Gold
This is amazing! Thank you so much!
Bright Side can never stop uploading videos
Thank you aloot!! 🙏
It was such a nice video.. Increased my information.. Liked it aloot👌💕
👍👍👍The more modern, the more has high quality of using, thank you for your sharing.
Yes this Wireless technology used to be commonplace before the last reset
ikr !!!
I've always wondered how this works thanks
Thanks bright side for teaching me this!
Good information...love your videos!
Oh, this is really curious. Cool!
Katrina Petrova...what are you doing here in all these humans?
Good Informative. Great pleasure to follow you.
thanks for your amazing videos !!!!
Who is disliking this type of informative and interesting video & why?! 🤷♂️
Brainless jerks
Didn't know about the other charging techniques. Nice.
Your linguistics skills is fabulus. I like it
I would like this type of charging on my bed cause i spend a lot of time on my bed.
Nice video!
One Of the best channel of TH-cam ❤️
My clock radio has a built-in wireless smartphone charger on its top surface. It is great!
I just got my phone out of a wireless charger when your video popped up
Just buy a charger
The video is amazing 🤩
Fantastic...📲👌
Hey Bright Side, can you make a video about why we need to “catch our breath” after physical exertion. You’ll probably never see this but if you do, I like your videos.
physical exertion costs energy
breathing process produce energy
more physical exertion, more breathing needed
Me watching this after I bought a wireless charger and want to see how it works 😆
Hey can you make a video on - Does charging your phone switched off makes it charge faster?..
Nice Videos Bright Side!...
This is helpful i needed this because my phones charger port broke
Nice!
how do you animate videos like this? what is the software
Bright Side is a knowledge hub for me
YOU ARE SO SMART
Which softer has been used to make this video would you tell me please
Interesting video...🤔💭
Nice😎
Nikola Tesla deserves more respect.
This has been used by Braun years ago on its rechargeable tooth brush!
Sooo awsome
With the car idea, what do we do with the batteries for waste? Is there a process to recycle? Or do batteries just end up in a land fill?
Thing NEVER change that fast , it takes awhile , I have seen alot of advances over the Last 50 years so I Have hope for the future
Hi bright side next video you should do a video on the Britannic support from your biggest fan
Which text- to - speech software u are using ?
Fun fact that i generated:
Putting your devices volume loud for long periods of time you'd probably lose more battery
ANOTHER GREAT VIDEO THAT MAKES A SAY HMHMHM!!!! THANKS
We just need to figure out how to turn lies into energy; politicians will finally be able to do something good for society providing free and unlimited energy!
Zoltanocortez It seems that this present world has an obsession with free stuff. “There’s no such thing as a free meal.” 😉
@@frankpichardo5299 nah. It seems people have an obsession with the dollar bill. People are too greedy and don't look out for their fellow men and women. They worship that dollar bill instead. They'd sell their souls and literally work their lives away for it. And rich people love that because they only give you a small crumb of the pie and you'll do ANYTHING they want. Meanwhile they continue to get even richer off of our hard work. Politicians and CEO's alike. But we're programmed to think that's how it's supposed to be...
They turn lies into disasters.
What a weird place for this...
They can do it with stress
0:53 I've heard that name in the new Ben ten
Dude he's one of the smartest men to have ever lived he made the system that transmits electricity to your house we have electricity in everyday use cause of him.
Nice video i love's your vedeos so much ❤❤❤❤❤😊😊😊🙂🙂🙂🙂
Hello disha soumya are u daughter of prabhat kumar
Bright side: QUICK charging and GOOD radius for charging
Me: wallet?
Wallet: No
It's only 19 euro here I have 1
Nice
Nickolas Tesla.... the most wonderful sintist
Hey Calder charge the headphones on wireless charging
Amaziiiiing
The car part of the video was pretty cool.
thanks for very professional videos .. it is a reusable video??
This video was a response to the iPhone going wireless!
I can't wait to flex my future charger on everbody at school
Well this has ages like a fine Italian red wine
Actually I was stuck with AD😆
Yes
03:28 I cant wait for this team of scientists to be awared a Nobel Price, in almost any video they appear seriously involved in the research.
You forgot to mention portable wireless charging, I have a charged power bank that charges wirelessly, as opposed to carrying a cord with me when I’m not home. $29 from Kmart, not bad!
Who love Tesla like here
GrassLand Creations.
What the heck is telsa? 😔
*It's Called as Tesla not Telsa kid*
Love bright side
Number one FAN
I would sing more with phone attached to my head
Technology is 💯👍✅🙂
Yes, gadgets from now a days, becomes more powerful. Its confusing what gadget you are going to buy
I thought the same (coil and induction )
I need to re open my 12th physics book 🙇♂ nikola is my hero
I literally only use a wireless charger cuz my charging port is kinda broken and I always have to wiggle the charger around to get it to work. Wireless charging is way better and faster for me.
Yeah, same
It does degrade the battery faster though using wireless charging compared to using a charging cable
3:12 how is it wireless charging if you need a charger?
Make a portable table for my recliner😀
One thing for sure is that I am going to be to old by the time this is main stream... I am going to be that old guy talking about the cables we use to have to charge with and that we had to actually plug in cars to charge them 😂😂😅😅😫😫.
Old , but gold lol. But I do hope we enjoy this in the near future
your video is great....but only want to say thay plz tell facts in simple language❤❤
Pls help.
My samsung s8 cannot work with wired fast charging,it takes nearly 5 hours to charge with a fast charger.Will it work with wireless charger.?
5:00 not the cace for the sansung galexy note 7
Today I have a test qbout the periodic table which has to do something with electric conductivity and stuff. Wish .e luck 😔✋
Good luck!
Does a samsung galaxy j7 prime have that coil?
I bought a wireless charger and the charge adapter for my phone on ebay. You have to remove the back cover of the phone and install the very thin charging coil, then re-install the back cover. I have heard that some phones come already setup for wireless charging. I wouldn't have bought it if I had known that when charging, (I didn't do my research) the phone gets pretty hot. After doing a search on the Internet, I found that other people have the same problem, and they say it can damage the battery. The phone gets hot while charging and I don't want to damage the battery, so it was a waste of time and money because I don't use the wireless charger. I don't know, but there could be some phones that are manufactured with wireless charging that don't get hot while charging. I was trying to come up with a solution to the phone getting hot. I think, if I could set up some kind of timer that would switch on and charge for a little while, then switch off for a while in between charging cycles, it wouldn't get a chance to heat up. It would take longer to charge that way, but if I just use the wireless charger at night, it wouldn't matter if it takes longer to charge.
I love bright side
if i had a wireless charger of my own i would be happy
When I think of EMFs, I think of microwaves. Does this mean I can charge my phone in a microwave? I thought it made your phone explode.
It is entirely possible that radiation can charge a phone. But the heat transferred in microwaves causes the phones battery to heat up. Causing implosions and fried circuits
It burns the phone speaking from experience
I learn every day from BRIGHT SIDE😄😄
Love wireless charging.
What if we replace copper with silver in wire less charger
So when sound wave chargers are available in stores all i have to do is scream at my phone and the charger? Seems pretty easy to me!😂😂
Khee kheee that laughter! 😁😁😁
Once wireless chargers becomes faster and actually wireless, I'll buy one.
Nikolai testa is the greatest Investor but underrated
I know a weird method of producing free electricity. If a bulb and its terminals is attached on a solar panel and if the bulb is given a power up,it may produce electricity even if its disconnected from charge
How does a bulb produce electricity?
Bulb shoulď be placed on solar panel
@@azwadmustahid1418 I see what you are saying that is pretty cool.
We might discover a hover vehicles in wireless future
Nikola tesla was ahead of his time💡
Man, how far has technology become?
Thor can instantly charge his phone
XD
He will make a phone explode instead like shezam did
Hahahaha
A wireless charging bed would be perfect 😂👌
True
It explains Electromagnetic Induction in this video
Yea ikr
Charging pad is much slower than the lightning cable for my iPhone 8 Plus.
We cannot replace power lines with wirelesss fields. It may cost A LOT
Probably wouldn’t be replaced. Like any new technology like this it’s usually slowly integrated in certain places then as the market grows and catches up and demand grows, the manufacturing becomes cheaper and more common until its widespread. Look at the spread of 5G right now. The idea has been around for a while but it’s been very niche. Now that apple and Samsung are putting it into devices, more people will want and use 5G so you’ll see more of it.
Yeah it’s cool
I would definitely want my bed as my charger
L😂L
THANK you. I am only learning tech. I would love to have a human GOOGLE ❤Smile...happy Valentine's day!
I wonder how much electricity Tesla used in his experiments versus created.
