Creating an inverter
Budget: €30 – €250 EUR
Hello There!
My name is Cosimo and I’m working on my own project about a jumping piece of aluminum placed on an electromagnet supplied with alternating current, like in the linked video at the minute 1:08.

I already replicated the experiment at home with the same electromagnet derived from a microwave’s transformer and supplying 220V at 50 Hz to it and I obtain the same effect (I was also able to measure the current flowing with a current clamp and it takes about 37.5 amperes).
But in my project i want to try and enhance the repulsion effect.
I know that this effect is based on Faraday’s law and on the induction equation “f.e.m.= magnetic flux/time” so you could make the aluminum part jump higher by giving the electromagnet more current (increasing the magnetic flux).
But I would like to see if the formula works also in the other way: so by keeping the same current and supplying a higher frequency (so by reducing time in the induction equation)
So I would need an inverter that can supply a higher frequency current (higher than 50Hz) to the electromagnet and keeping the 220V from the home power socket and see if the piece of aluminum actually jumps higher.
I’m sorry if I wasn’t able to explain good enough for you to understand, so I’ll be more than happy to answer any question or doubt that you would have.
