aluminium object dances in strong magnetic field and aluminium disk spins easy in magnetic field.

A nice high frequency resistor and partly filter, if there id any need to do that mechanically. And it needs to be tuned to the specific use.

what do you think happens to metal dust or metal shavings or small metal discs, or metal flakes. not much different to acoustic levitation tbh. I think you could even use some commercial induction stove to do that. off the shelf I mean. at least if you want to get the high frequency ac current circuits. at some decent power level, normally about 2kW. hmh maybe metal bearing balls in a plastic/glass jar on top of the coil. maybe a nice bearing ball mill. no moving parts. also simple wood cutting experiment with the spinning motor metal blade. sounds like its an induction motor. is the disc aluminium, if yes then try steel disc. or a saw blade. its iron cored then, multiplied the magnetic field effect. and eddy currents. the bearing balls should levitate.

No bullshit, full disclosure. Very nice, thank you for this. 🙂

How. To make. Full tutorial please. Sir

Hello! What kind of DC/AC converter are you using for experiments? Thyristors with NE555 or PWM and half-bridge with MOSFETs and MCU? The simplest solution - a module of class D audio amplifier with a sine wave RC generator.

[@smailbluestar]

@@andrewandrosow4797 D class audio amplifier . sine wave. You can use every power amplifier. Connect the Input of amplifier to the audio signal generator or install audio signal generator app on phone and connect the output of headphone to the input of amplifier

How much is the AMPs ?

[@smailbluestar]

@@tchobanovivo5679 in this experiment I used 1000 Hertz current. My clamp ammeter doesn't measure high frequency current carefully

[@joeldsouza4860]

How many amps does it need?

[@smailbluestar]

@@joeldsouza4860 it works by more than 1000 Hertz. my clamp ammeter doesn't measure exactly.
