WebIs it possible to make energy with magnets? Magnetic fields can be used to make electricity Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

Do magnets ever lose their magnetism? - PhysLink.com

WebAt high temperatures, any magnet will lose its magnetization rather quickly (in a matter of minutes, if the temperature is high). Answer 2: Magnets stay magnetized until something destabilizes them. The constant jostling of molecules (i.e. heat) slowly disorganizes the magnetic domains in a magnet, and this happens faster the hotter the magnet. WebThe temperature at which the magnet no longer holds its field is known as the Curie point. Another way to make a magnet lose its magnetic field is by hitting it. The impacts on the magnet will ruin the needed configuration of the electrons and the magnetic field will weaken and possibly be lost. The other group is called temporary magnets. fisheries hartbeespoort https://andysbooks.org
