Came here expecting another 5 minute crafts type project, didnt expect something that is actually useful. I didn't believe in the slightest that it would be that strong either...
Yes. I showed this to my 6th-grade students. I kinda skipped some of the unnecessary making part so that they can focus more on the video. They really enjoyed watching it, and especially loved the ending part where two men do lots of experiments with the electromagnet!
As I already said you are doing a thing which is an entire industry does with the help of designers, engineers, CAD designs, prototypes and CNC perfection but you all did it like building a Lego toy. God gifted you great knowledge and resources.
Yes as the coil turns magnetic, it heats and repeated contraction and expansion will result in it being separated from the steel top as the cofficient of expansion for both resin and steel top varies. to make it stronger, consider welding a steel plate to the top one.
Couple of suggestions: If you ever drill a hole, get a countersink in your battery powered drill and get rid of those sharp edges around the holes. And if you ever put a cable through a part like that, put a strain relief there, the typical go-through-plate reliefs also provide protection from the wire abrasing against the plate.
@@richardmoeller5351 actually they removed a coil and a big part of the core so the reactance is lower. this thing is probably drawing ludicrous amounts of current and probably heat up real fast (unless he powers it with current limited dc)
each of the transformers from the microwaves has a positive and negative. He just attached each of the positives and negatives together then fed them into the main female plug. which plugged into a male adapter which probably gave out the same power as that of a house socket.
I made one with 5 trans and it was still cool after 10 hrs operation. EM force produces very small amt of heat. The heat gets dissipated through the casing metal.
You guys are insanely brilliant. The stuff you make and the way you make it look easy is ridiculous. Make a fricking spaceship, seriously. I know you can do it
@@rossyb_youtube AC would be much worse than DC because you have to imagine that with DC the charge moves in one direction and this movement creates the magnetic field which points either up or down. With alternating current you force the magnetic field's direction to change all the time and this creates a loss of power which is proportional to the frequency of the AC.
@The Great Cornholio but therefore you would need to connect it backwords - also now the plug is delivering the voltage that's means it would be possible to touch a live contact (if its just 12v as i think it wont matter)
You guys should make a super powerful Blender out of a 5 gallon bucket. ha. Something that would blow the Vitamix and Blendtech out of the water. You will need something like that for parties. Just saying
@@inrg3688 It will not pick items up due to mains (in us) being 60hz, which means that the direction of current changes 60 times a second. Because this means that the polarity of the electromagnet will change 60 times a second, it will not pick items up like shown in the video

Yes, it is possible to adapt this concept for a levitating vehicle, though several engineering challenges and design optimizations need to be addressed. Here's a breakdown of the feasibility and how a Halbach array could assist: 1. Principle of Operation Eddy Current Levitation works by inducing eddy currents in a conductive plate (aluminum) using alternating magnetic fields, which generates a repulsive force and levitates the plate. In your current setup, the transformers generate a 60 Hz alternating magnetic field, which induces eddy currents in the aluminum plate, causing it to levitate. 2. Challenges for a Levitating Vehicle Sustained Levitation and Stability: To levitate a person and the associated vehicle structure, you'd need significant lift, which means higher currents and optimized magnetic field strength. Overheating Issues: With higher currents (4A to 6A per transformer), overheating is a problem. Active cooling (forced-air or liquid cooling) would likely be necessary for continuous operation. Dynamic Movement: Moving the levitating vehicle requires a method to vary the magnetic fields or induce lateral motion. This could be achieved by modifying the frequency or phase of the AC current to create directional thrust. Alternatively, a motorized or magnetic propulsion system could be integrated for lateral motion. 3. Role of a Halbach Array Enhanced Lift Efficiency: A Halbach array focuses the magnetic field on one side while canceling it on the other. Placing a Halbach array on the vehicle would enhance the field strength directed toward the aluminum plate, improving the eddy current induction and providing stronger, more efficient lift. Reduced Energy Losses: By focusing the magnetic field downward, less energy is wasted in stray fields. This increases the overall efficiency of levitation. Stability Control: Halbach arrays can also assist in achieving better stability and control of the levitating vehicle by ensuring a consistent magnetic profile over the surface of the aluminum plate. 4. System Design Proposal Vehicle Structure: The vehicle base can house the Halbach arrays or electromagnets driven by high-frequency AC power. Ensure the structure can withstand the forces generated by the magnetic fields and accommodate a cooling system. Track/Plate: Use a continuous, smooth, thick aluminum track that moves with the vehicle, ensuring consistent eddy current induction. Thicker plates can provide more lift due to increased induced currents. Power Supply and Control: Utilize a high-frequency inverter to drive the system at frequencies higher than 60 Hz (e.g., 200 Hz to 1 kHz), which improves levitation height and efficiency for thinner aluminum tracks. Incorporate a series-resonant circuit with adjustable capacitance to optimize lift and current draw. 5. Considerations Safety: Ensure safety measures for high-voltage operations. Cooling: Implement robust cooling for transformers and magnetic components to avoid overheating. Weight Limits: Practical limitations on the weight that can be levitated, considering power requirements and system efficiency. Conclusion Yes, you can design a levitating vehicle using this approach, and a Halbach array would significantly improve efficiency and control. However, high-frequency AC power, cooling systems, and precise engineering for stability and dynamic control are critical for success.
Sergey Sorokin thank you, do you know how to make a power supply for this, as soon as i hooked it up to my dc wall outlet power supply it fried my powersupply
Awesome project! The uses for old MOTs never cease to amaze me... What is the total capacity of it? It's obviously enough to life both you guys & a heavy plate of steel, but did you test to see just how much it would hold until it fails? (Small car?)
If you touch 24V DC it is completely safe. But not safe for the power supply itself as it can get shorted by literally anything from metal that touches it
очень аккуратно сделано, достойные проекты у автора, но как иногда говорят в рунете, тема сисек не раскрыта) how many does it can lift? how much is voltage supply?
I have seen a few of these transformer type pickup magnets, but I give you a thumb up for shortening the TRF core for further reducing magnetic circuit resistance.
You've got great hands man! That looks professional! Seeing how you salvaged those parts from a microwave and made this tool reminded me of those Discovery channel prehistoric shows with cavemen - but in a more recent form, lol. GJ

Hi, great work, how did you connect the coils parallel or series, and at which voltage level?
It's Amazing and powerful.
how much voltage I need for each transformarter?
Ok, that is totally bad ass!! Amazing build and finishing.
microwave is a hell of paid actor 😀😄
Great video! I love how this is all info, but ZERO talking. Unlike most of youtube.

I wonder how long it takes for the coils to heat up under load
my question too.
Casing acts like a heatsink.
I made one with 5 trans and it was still cool after 10 hrs operation. EM force produces very small amt of heat. The heat gets dissipated through the casing metal.
Great Work & Nice Shot
Wow strong magnet class)))
I wish people had this kind of inventiveness everywhere
3:20, why did you use female plug on the magnet. Does it mean that you have a voltage on the male plug pins?
Yeah
This is male and no female
You guys are insanely brilliant. The stuff you make and the way you make it look easy is ridiculous. Make a fricking spaceship, seriously. I know you can do it
Am I missing something? I thought electromagnets required DC current to operate yet I see no diodes and DC supply is not mentioned. What gives?

With alternating current you force the magnetic field's direction to change all the time and this creates a loss of power which is proportional to the frequency of the AC.
Autoinductance delays the current, if you get a delay of 90 degrees, you can achieve permanent attraction
@@rossyb_youtube read the blog it uses 48v dc

What material did you add at 3:24 Is it Epoxy ??? please answer
Bad ass man. I have a couple of questions. Is it using direct mains voltage? does it get warm after heavy use such as after 10 or 20 minutes?
No, because electromagnets don't work with AC.
@@deafkite638 yes they do
@@inrg3688 It will not pick items up due to mains (in us) being 60hz, which means that the direction of current changes 60 times a second. Because this means that the polarity of the electromagnet will change 60 times a second, it will not pick items up like shown in the video

What voltage is applied- AC or DC?
any ưould work

The method for the plug is kinda umsafe....
Angryjoshi16 it is probably to avoid pluging it to AC mains by mistake, as the magnet works on 48v, as said on their site
@@yahnsolo also, only 48 Volts on the plug makes it safe. Probably still not nice to touch, but 50v is considered a safe voltage.

why is the female plug on the magnet side? pretty unsafe
fab-ster it's low voltage dc
why is it unsafe tho?
Robert Combs because that means the side wich delivers power is male. Aka two metal pins under voltage. Aka you can touch them when they're powered.
If you touch 24V DC it is completely safe. But not safe for the power supply itself as it can get shorted by literally anything from metal that touches it
whats the correct way to hook this thing up guys.... ?.. thanks .....much peace n love
