The north pole and the south pole.

Iron, steel, cobalt and nickel.

Because steel keeps its magnetism for a long time.

What is an induced magnet?

A material that becomes magnetic in a magnetic field but loses most or all magnetism when the field is removed.

How can you test if an object is a magnet rather than just a magnetic material?

Look for repulsion. Only a magnet can repel another magnet; plain magnetic materials are only attracted.

Where is the magnetic force strongest on a bar magnet?

At the poles.

What happens if you cut a bar magnet into two pieces?

You get two smaller magnets, each with a north pole and a south pole.

No. They only attract magnetic materials such as iron, steel, cobalt and nickel.
