This is done by passing electric current through a solenoid which surrounds a magnetic material such as soft iron. a magnetized paper clip. answer choices . False. 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. Magnets and electromagnets are used in many devices. True. ... Q. A magnet contains two poles that is the North Pole and the South Pole. Electromagnet An electromagnet is a type of magnet that is made from electric current. SURVEY . Scrapyard cranes have powerful electromagnets that lift metal car bodies with ease. Answer the following True or False questions about magnets and electromagnets: Heating or hitting a permanent magnet can ruin it. When the strength of the magnetic field changes, the _____between the coil and the permanent magnet changes. True or False?

Which is a permanent magnet? Explanation: Brainliest plz New questions in Chemistry. Iron is a good metal to use to make an electromagnet. The north pole of one magnet will attract the north pole of another magnet. 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. True. C Magnetic Resonance Imaging machines use very powerful electromagnets to … True or False: A nail with a wire wrapped around it is an electromagnet. true . True.
