AlonsoCastillo AlonsoCastillo 7 minutes ago ... You can make a temporary magnet by stroking apiece of iron or steel (such as a needle) along with a permanent magnet. a magnetized paper clip. answer choices . Electromagnet is a permanent magnet. Magnetic field lines run from the south towards the North Pole. 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. Play this game to review Magnetism. False. True or False: A big magnet has a stronger force than a small magnet. A. strengthen an electromagnet's magnetic field. When the strength of the magnetic field changes, the _____between the coil and the permanent magnet changes. True or False: A nail with a wire wrapped around it is an electromagnet. SURVEY . A magnet contains two poles that is the North Pole and the South Pole. answer choices . This is done by passing electric current through a solenoid which surrounds a magnetic material such as soft iron. Which is a permanent magnet? True or False? True or False Share with your friends. Explanation: Brainliest plz New questions in Chemistry. A magnet must touch matter in order to interact with it. false . Magnets and electromagnets are used in many devices. False. When an electric current flows in a wire, it creates a magnetic field around the wire. , the _____between the coil and the South pole as soft an electromagnet is a permanent magnet true or false by electric.
