@@hyperz_pro8970 No. There are mainly two types of magnets: Permanent/hard magnets and Temporary/soft magnets. Permanent magnets are hard to magnetize, but once magnetized are very hard to demagnetize. Soft magnets are easy to magnetize and demagnetize. So no, all magnets are not permanent magnets. Hope this helps you!
*Please answer this -* So I study geography, which has a lot of content now but I want to do well in it. I don't think I can revise everything by the exams, and I am not taking it next year, but, as i said, I want to get a decent grade. Should I spend more time on it, or keep going as I am? Thanks again sir!
how can a magnetic material become a permanent magnet? since i know that a material must be in the magnetic field of the permanent magnet to become induced but i dont know how one magnet becomes permanent.
In the absence of an external magnetic field, a compass needle will always point towards the magnetic north (which is near the North Pole). So we say that it points North to South (which is the other pole).
no offence but if you are 10 why are you watching gcse content????? please please please enjoy your life now whilst you still can, take it from someone who knows
That's not correct. Steel (which as you correctly point out, and I state in the video, is an alloy of iron) is a magnetic MATERIAL. There are only 3 magnetic METALS. That's why I say "magnetic material" in the video and that's why it says "magnetic material" in the AQA spec.
Oh sorry, my sincere apologies. I did not know steel was still considered a magnetic material. I was taught since primary that the only 3 magnetic materials as Iron, nickel and cobalt. Terribly sorry.
No problem. It is a confusing statement to be honest, as you could count any magnetic material (for example neodymium alloys) so I don't know why steel is specifically singled out on the spec but it is. Anyway I hope that you found the rest of the video useful.
Because in the absence of any other magnet, the compass will always point in the North-South direction ie in the direction of the Earth's magnetic field.

Thanks so much!
this is rly helpful
night before the exam, thank you!!
okay but are we seriously having trouble remembering three elements

You are the best revision source on the internet! Glad my teacher recommended you!!!
Thanks for the comment. I'd appreciate it if you said thanks to your teacher for me.
You have recieved revelation.
Use it wisely

Oh my god ! Are you even human??? How could a human brain comprehend that much of complexity? You have the ability to defeat Thanos and Shaggy.
Iron cobalt nickel steels they all have magnetic fields
i've got my physics paper 2 tomorrow, which is my last science exam. thank you for all your help, sir. you've been a lifesaver :)
This guy is the best source during my GCSEs specially now during the pandemic thank you 😊
SOOO glad you have started this topic
physcis paper 2 is my last GCSE's exam. Thank you very much sir for helping me. All the best u guys.
hope u did well
finally a good science video with a discernable voice, thank you for the extra knowledge!
Anyone else in the pandemic and the teacher gives you this link?
Yeah lmao
Here
Aye
This guy is so useful 😂
If I pass my physics test it’ll be because of him
is a magnet and a permanent magnet the same

@@aadityaharikrishnan9970 permanent magnets also produce their own magnetic field
Thanks again this is helping lots with my revision for MOCs at the moment :)
your saving my gcse son
my man is gonna save my exams
Ur videos r best on wholeeeeeee TH-cam
Friggin love this guy👨❤️💋👨
watching all the physics videos a few hours before the exam 😭
genuinely this incredible man should get a knighthood
Thank you for the help

@Qu3en_A Geography's a science too and his question wasn't based on any geography content but studying overall
i wonder if this guy knows he has become a national meme
yh our classmates bet on if he is smiling at the start
hes a national treasure too though
International*
which meme
The goat
can i ask????
does a temporary magnet have a magnetic field
Yes they do.
Science is amazingggg 🤩🤩🤩
how can a magnetic material become a permanent magnet? since i know that a material must be in the magnetic field of the permanent magnet to become induced but i dont know how one magnet becomes permanent.
Atchek You don't need to know this for GCSE but I think it's because the electrons have an aligned spin or something.
its something to do with the magnetic domains in the metal becoming aligned when in a magnetic field but you don't need to know this for gcse
What do you mean when you say the compass points in the North south direction towards the end of the video?
In the absence of an external magnetic field, a compass needle will always point towards the magnetic north (which is near the North Pole). So we say that it points North to South (which is the other pole).
Thank you!
Why does the compass needle move when it is placed near the bar magnet?
Because a compass needle contains a tiny bar magnet so it is either attracted or repelled by the other bar magnet, causing the compass needle to move.
Thank you so much!
hey if anyone from my class sees this: hi
you carry half the lessons in my class
Are you going to be covering the waves topic?
The waves topic was done weeks ago and there's a playlist on it. Let me know if you can't find it.

Thank You!! Helped me understand. I am 10 btw

ThaNks for video it's amazing 🙃🙃🙃
No, there are only 3 magnetic materials- Iron, Nickel and Cobalt. Steel is an alloy of iron so without it won't be magnetic.
That's not correct. Steel (which as you correctly point out, and I state in the video, is an alloy of iron) is a magnetic MATERIAL. There are only 3 magnetic METALS. That's why I say "magnetic material" in the video and that's why it says "magnetic material" in the AQA spec.

Ok, Btw is the circuit breaker on the specification? because we were made to copy it down in class so idk
Dummey Titan no
THIS ABSOLUTE UNIT
cheers mate
Mau i ask what the straight line in the magnetic field is.
Hi, why are the magnetic fields stronger when they’re closing together?????
Because they are close so the force is stronger to act on them??
Does't the north labelled part (south pole of compass labelled north) of the compass faces north to show the north side?
btw your videos are great, and I'm talking about video at 2:30
good information tnx
Nice video, but why does holding a magnetic compass away from a magnet suggest that the Earth has its own magnetic field
Because in the absence of any other magnet, the compass will always point in the North-South direction ie in the direction of the Earth's magnetic field.
@@Freesciencelessons Why is this?
@@Rishi-qk2qp bruh he just explained it
1:18 where it says "then it will experience a force of attraction towards the magnet" , by "it" does it refer to the magnetic field?
It refers to the iron
Where's the worksheet questions may I ask
is it essential to know how a compass works?
Only that it contains a small bar magnet and points in the direction of the Earth's magnetic field.
When is physics topic 7 going to finish
if you place a thing that’s not iron, cobalt, nickel or steel, will it become an induced magnet??
no
1 day left
