An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it.
You can make your own electro-magnet with a battery, some wire and a large nail.

What is an advantage of using an electromagnet rather than a regular magnet?
A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.

Advantage of using electromagnet in an electric motor rather than a permanent magnet?
convert electrical energy to energy of motion...! the usage of an electromagnet allows us to control the flow of electrons to the electric rotor,thereby allowing us to control the working of the rotor,whereas with a permanent magnet there will be a continuous supply of energy which can be stopped only if the magnet is damaged or heated.
