TEMPORARY MAGNET:
temporary magnet are those which act like a permanent magnet when they are within a strong magnetic field,but lose there magnetic field disappears. Examples would be paperclips and nails and other
TEMPORARY MAGNET:
easy to magnetize,quick to lose magnetism
nickel,cobalt,iron EXAMPLE:ALNiCo(alloy)
PERMANENT MAGNET:
material that keepsits magnetic properties,even when it is not close to other magnet
magnetite-natural magnetic rock(LODESTONE)
example-bar magnet,refrigerator magnet,horse shoe
