How does temperature affect magnetism

WebJan 5, 2016 · An important part of the relationship between magnets and temperature is the fact that heating the magnet causes its molecules to become more disorderly. Magnets are dipoles, which means they have an opposite charge, or magnetic direction, at each end. This is a result of most of the magnetic molecules facing the same direction. WebNow the magnetic field B → mag B → mag points toward the magnet instead of toward the coil. As the magnet approaches the coil, it causes the left-pointing magnetic field in the coil to increase. Lenz’s law tells us that the emf induced in the coil will drive a current in the direction that creates a magnetic field pointing to the right.
