Answer:

An electromagnet is useful because it can be turned on and off easily (using an electric current), whereas a permanent magnet cannot be turned off and will continue to affect its immediate environment. Different alloys act differently. Iron stops being an electromagnet very quickly, but steel takes time to wear off.
