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.
Will a magnet still be a magnet if it is melted?
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
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.
Can a magnet loose its magnetism?
Yes, if you: -drop it many times -hammer it many times -heat it over a flame
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
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?
No it wont but if the water is hot then it will lose its magnetism
What type of magnet has iron in it?

What is a magnet's magnetism the strongest?
