Magnetism is caused when all the atoms of a metal like lodestone, iron, cobalt, nickel, or gadolinium are lined up in one direction. If this happens during the cooling process, after being melted, it will result in a permanent magnet

What causes a magnet to loose its magnetism?
high temperature, AC magnetic fields, mechanical shocks, and physical distortion.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
At the centre of a bar magnet magnetism is?
zero
How does the weight of a magnet affect its strength?
Magnetism is the number of magnetic moments per unit of volume. It is the volume of the magnet which determines the magnetism. If an object has great weight and great volume, it will be a strong magnet. If an object has great weight but lesser volume, the magnetism will be weaker.

What causes magnets to attract the refridgereator?
The force is called "magnetism". The refrigerator is not magnetic, but the magnet will temporarily induce magnetism in the refrigerator's metal - the part that is close to the magnet.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
Would a magnet to last longer in hot or cold weather?
It would last longer in cold weather because heating causes a magnet to lose its magnetism.
What propeties do a magnet have?

Magnetism is stronger at what place of the magnet?
A magnets magnetism is strongest at the poles.
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
