Magnets that always have their magnetic force
question

Temporary Magnets
Temporary Magnets
answer

Temporary magnets are ones that become temporarily temporarily magnetized when brought near a permanent magnet. if a magnet is used to pick up a paper clip, the paper clip will be become magnetized too, and it will be able to pick up another paper clip. Once the permanent magnet is removed the paperclips lose their magnetic properties.
question

Electromagnet
Electromagnet
answer

This type of magnet is a permanent magnet only when an electrical current runs through it. the strength of the magnet is dependent on the strength of the electric current.
question

Superconductors
answer

Very very strong electromagnet
question

Magnetic field
Magnetic field
answer

The space around a magnet or an electric charge within which the force of magnetism acts
question

Lines of force
answer

The lines of force of a magnetic field will differ based on the shape of the magnet . The line comes out of the North Pole and re enter the magnet through the south pole. A magnetic field is strongest at these two poles.
