To make this electromagnet stronger you could. answer choices . a magnetized paper clip. answer choices . True or False? use less wire. This is done by passing electric current through a solenoid which surrounds a magnetic material such as soft iron. 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. answer choices . Magnets and electromagnets are used in many devices. answer explanation . Dear Student , Electromagnet is not a permanent magnet as when the current is withdrawn then the magnetism property is gone . False. What is the name of a magnet that stays magnetic only while it touches a permanent magnet, or one that is magnetic for a very short time. False. answer choices . The north pole of one magnet will attract the north pole of another magnet. True or False? An Electromagnet need electricity and a permanent magnet doesn't Electromagnets are less useful. True or False: A nail with a wire wrapped around it is an electromagnet. true . a magnetized iron nail. Which is a permanent magnet? false. Electromagnets. A magnet must touch matter in order to interact with it. Electromagnets can be turned off and on. Iron is a good metal to use to make an electromagnet. Magnets and electromagnets are used in many devices. alternatives . A permanent magnet stays a magnet forever and a Electromagnet doesn't. A magnet contains two poles that is the North Pole and the South Pole. ... Q. True or False Share with your friends.
