What is the thing that weakens a magnet?
Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
Does magnet size affect the strength of a magnet?
Yes it does!
What weakens a magnet?
A magnet can be weakened by heat or dropping it alot of times
Does the temorature of the magnet affect the strength of the magnet?
No the temperature doesn't the size does.
How does heat affect magnetism?
If one continously heats a particular magnet to high temperatures or long time or both, it loses it magnetism because the particles get excited and start forming no-magnetic arrangements.
Does a magnet in use produce heat?
no
Does a magnet conduct heat?
yes, it does .......
Will a ladycare magnet interfere with a Mirena coil?
A magnet will not affect the Mirena IUD.
Will a magnet affect a credit card?
yes but it depends on the type of magnet and how strong it is
Can a magnet affect the circumference?
In general, no.
Does the shape of the magnet affect its strength?
no
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.
