The biggest difference between a permanent magnet and an electromagnet in industrial applications is the on-off switch. ... The magnetism in an electromagnet is created by current running through a coil of insulated wire that is wound around a piece of "soft" magnetic material.

The basic difference between electromagnet and natural magnet is that when we pass electric current through a solenoid or any other iron substance then it behaves like a magnet and its magnetic  power is  for sometime but in natural magnet power is kept for long time and they are more powerful than electromagnet.
