Question

how will you prepare "free energy bulb using magnet " home made. give scientific reason behind this.

Answer 1

We make a loop of copper wire with many turns in it. It has a radius of a few centimeters or more. We connect a small bulb with very low wattage and voltage ratings to the wire in series. Then we fix the copper wire loop or coil, vertically. 

 Now we take a small bar magnet and move it forward and backward through the wire loop. It should be done with a good speed. Due to the phenomenon of electromagnetic induction (Faraday's Induction) emf or electromotive force is generated.  Thus current flows through the wire and the bulb lights up.
