Do you have any idea what is a permanent magnet is? Well, it is very simple. It is always a magnet that you cannot switch on and off. It will always stay a magnet unlike an electromagnet. If you break a magnet in two, then both of the magnets will still be magnets. An electromagnet is different If you were in a junkyard and if you use an electromagnet magnet to pick up pieces of metal then... the magnet will not let go of the metal pieces unless the magnet is switched off. Permanent magnets are not as useful as electromagnets.
