From this experiment, we conclude that a current carrying wire also behaves like a magnet. Once the
of current is stopped, the magnetic property also disappears.
OTE: Just as a straight current carrying wire behaves as a magnet, a helical current carrying coil
also behaves like a magnet. show explain the
