Play this game to review Magnetism. True or False? answer choices . An Electromagnet is called as a temporary magnet, because electromagnet is made up of insulated copper wire wrapped around soft iron, which allows current to flow in it and at that moment iron gains it magnetic properties and when the current is switched off, then there will be no flow of current and hence iron loses its magnetic properties. Electromagnets can be turned off and on. True or False Share with your friends. Magnetic field lines run from the south towards the North Pole. answer choices . False. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet. Regards. true .
