An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
It requires a current through a coil of wires.
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
An electromagnet can be turned on and off by controlling the electric current, allowing for greater control and versatility in its applications. Additionally, the strength of an electromagnet can be easily adjusted by changing the current, making it more powerful than a bar magnet. Electromagnets can also be designed to have specific shapes and sizes to suit different needs.

a electromagnet is bigger than a bar magnet

I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.

It will pick up the nails the same way a bar magnet would do!
bar
electromagnets carry more energy and are mainly found in motors................
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?

The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
