How does heat affect magnetism?

When you heat a magnet, the particles in the magnetic material get excited and their formation (arrangement) within the material changes. As a result, the magnet loses its magnetic properties. In other words, a magnet is destroyed when you heat it.


Does temperature affect a magnet?

temperature does not affect the magnet.


Does changing the temperature of a magnet affect its force?

Yes it does if you freeze the magnet the magnetic field gets larger and if you heat it up the magnetic field gets smaller

Why does freezing a magnet affect the strength of a magnet?

Because it freezes its particlesAnswer 2 The above answer doesn't say why the strength of a magnet is affected by freezing it. I didn't know that magnets wereaffected by freezing - I can't see why they should be. Heat, now that's a different matter.


How does temperature affect a magnet?

Heat, because it affects magnetic molecules, causes a drop in magnetic field strength. Cooling a magnet has the opposite effect: reducing the resistance in the molecules and increasing the net field strength.

Can hot and cold affect magnets?

yes it does affect magnets ! though cold has little effect on the properties of a magnet , but heat drastically brings about change in properties of a magnet. With increasing temperature, the magnet will gradually lose magnetization until a certain temperature (called the Curie temperature) where the magnetization goes away entirely. In addition to this effect, the domains of the magnet will have a greater chance of changing orientation, further weakening the overall magnetic effect.

Why does heating a magnet decrease its magnetic field?

because when you heat the magnet the heat causes the domains to detatch and not alighn so the magnetic field decreases
