How does temperature affect magnetism
WebAs temperature increases (from absolute zero), the distance from the nucleus, and other electrons, increases so they follow a longer path and have less influence on each other, and magnetic properties of metallic magnets generally decrease.

WebThe purpose of this project is to learn more about the properties of magnets when they are subjected to different temperatures. Does the temperature of a magnet have any effect on its strength? Methods/Materials Hypothesis: 1. The strength of a magnet is affected by temperature. 2. As the temperature of a magnet increases, it becomes stronger. 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.
