Electricity and Magnetism

Magnetism is:

• the region around a magnet in which magnetic forces act
• a magnet made of a material that keeps it magnetism all the time
• the attraction of a magnet for another object
• a magnet made of a material that can lose its magnetism

A permanent magnet is:

• the region around a magnet in which magnetic forces act
• a magnet made of a material that keeps it magnetism all the time
• the attraction of a magnet for another object
• a magnet made of a material that can lose its magnetism

A temporary magnet is:

• the region around a magnet in which magnetic forces act
• a magnet made of a material that keeps it magnetism all the time
• the attraction of a magnet for another object
• a magnet made of a material that can lose its magnetism

A magnetic field is:

• the region around a magnet in which magnetic forces act
• a magnet made of a material that keeps it magnetism all the time
• the attraction of a magnet for another object
• a magnet made of a material that can lose its magnetism

If you put the south end of one magnet against the north end of another magnet the magnets will

• do nothing
• be attracted to each other
• repel each other
• break

If you put the south end of one magnet against the south end of another magnet the magnets will

• do nothing
• be attracted to each other
• repel each other
• break

If you put the north end of one magnet against the north end of another magnet the magnets will

• do nothing
• be attracted to each other
• repel each other
• break

An electromagnet is an example of

• a permanent magnet
• a temporary magnet
• a magnet that can pick up all types of metals
• none of the above
