I have a A4 22mm think metallic sheet, how do I magnetize it?
If it is aluminium, forget it. What material is it?
there r two methods to magnetise any substance, they r direct method and indirect method in direct method we used a bar magnet make at any two opposite sides of a4 size metal sheet rubbing re thematically with bar magnet then we make that a4 size metal sheet as magnet in indirect method we have to use power supply and a piece of copper wire in this processes we wound a4 size metal sheet with cupper wire and connect it to a continuos power supply,because of closed path of copper wire a4 size metal sheet devolpe its own flux and act as magnet
