Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
First chose is meteor and the second one is asteroids
Answer:
Maybe when you bump into the refrigerator and the magnet falls?
Explanation:
This is an example of you interacting with electromagnetics because you must have bumped into something and made a magnet fall.
I hope it helps?
If it does help can I have a brainliest?
Answer:
A.C → Alternating current.
D.C → Direct current
Explanation:
A.C is an abbreviation for Alternating current.
Alternating current is a type of current that flows sinusoidally or current that changes direction with time.
D.C is an abbreviation for Direct current.
This type of current flows only in one direction, i.e it doesn't change direction with time.
A rectifier can be used to convert A.C to D.C, allowing it to flow in one direction.
