get a choclate bar melt it place in a magnet shaped mold with bits of steel in it and cook and freeze
A spinning magnet inside a coil of copper wire will produce electricity.
It is weird
no
magnet produce emf it maintain the resistance as same
When the external magnetic field is removed, the magnetic domain in a magnet can produce a weaker magnet due to randomization of the magnetic moments within the domains, causing them to lose alignment. This results in a decrease in the overall magnetic field strength of the magnet.
Well, Many things can produce electricity. An easy way to produce electricity is to get a coil and pass a bar magnet through it.
When a magnet is stationary near a wire, it can produce current in the wire through electromagnetic induction. This happens when the magnetic field from the magnet interacts with the electrons in the wire, causing them to move and create an electric current.
Electricity can be produced by various methods such as generators, batteries, and solar panels, which can then be used to power a magnet.
