In depends upon how hot you are talking about. Cold would be my best answer in general. If you are comparing the magnetism between say 10 below zero and 100 F then there would be no discernable difference. If you should heat the metal to red-hot, the magnetism would be lost after the metal has cooled.
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
Several factors can weaken the magnetism in a magnet such as being stored close to heat, strong electrical currents, other magnets, or radiation. Over time magnet materials lose a very small amount of magnetism.
none
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
it will lose its magnetism OR it will get weaker
Magnets can lose their properties when exposed to high temperatures, physical impacts, or strong demagnetizing magnetic fields. Additionally, corrosion and aging of the material can also contribute to the loss of magnetism in a magnet.
A magnet looses its power when heated.
It loses its charged.
Magnets should not be heated or hammered because it disturbs alignment
Yes.
temporary magnets
temporary magnets
Yes, because electromagnets can lose their magnetism.

Yes, magnets can lose strength over time due to factors such as exposure to heat, physical damage, or demagnetization.
Yes, magnets can lose their power over time due to factors such as exposure to heat, moisture, and physical damage.
