1 Answer

Answer :

 A coil of many turns of insulated copper wire wrapped in
the shaped of cylinder is called a solenoid.
 The magnetic field lines in a solenoid through which
current is passed.
 These lines are similar to bar magnet.
 Properties are same as bar magnet.
 One end of the South Pole and other end of North Pole.
 If the rod is hard steel and magnetic field is strong then
permanent magnet can be produced.
 Permanent magnets are made up of carbon steel,
chromium steel, cobalt, tungsten steel and some alloy.
