What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
Is electromagnets are natural magnets?
The magnetism of an electromagnet is natural (it comes out of the laws of physics), but the magnetism disappears when the electricity is turned off - it is not a permanent magnetism.
Which mineral component sustains permanent magnetism?
quartz
Permanent magnets and electromagnets both hold their magnetism for a long period?
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
What is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
Material which retains its magnetism after the source magnetism is removed?
Those are called permanent magnets. Due to their metallic property to exchange electrons between the atoms the material acquires a permanent one sided quantum spin, producing permanent magnetic field.
What role do electrons play in magnetism?
Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).Magnetism is produced through electric currents.

How can the magnetism of a permanent magnet be weakened or removed?
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
Both permanent magnets and electromagnets hold their magnetism for a long period of time.?
false
What type of magnets are harder to magnets but retains magnetism much longer?
permanent magnets
