Electromagnetic force is energy created by the movement of electrically-charged atomic particles (protons and electrons). Whenever this type of energy is being released, there is both a flow (current) of charged particles, usually electrons, and a magnetic field that represents their flow in closed paths.
The basic form of electromagnetism is the attraction between charged particles in an atom: the protons (+) and electrons (-). The protons repel each other but are held in place by another force, the strong nuclear force. The electrons are held in their orbitals by attraction to the protons, and kept separate as they repel the other electrons.
The alignment of these charges in a number of atoms creates a magnetic field, and the motion of a magnetic field can generate an electric current. Conversely, the application of a flow of current can generate a magnetic field.

What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
Does an electromagnet use an electric force or a magnetic force?
it uses electric force
How can you make an electromagnet's pulling force stronger?
An electromagnet's pulling force can be made stronger by introducing iron core in it.It increases the magnetic pull.
Why magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
The space around a magnet where the force of the magnet acts is a?
electromagnet
What are 3 ways the force of an electromagnet can be controlled?
I like dolphins, ponies, and unicorns
How does a circuit breaker use an electromagnet?
The electromagnet in the circuit breaker is used for instantaneous tripping if short-circuit condition arises. At defined current level the electromagnet develops the force high enough to cause the tripping of the mechanism.
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
Does an electromagnet keep is force when the electricity goes off?
no because you need electricity to turn it on
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
Do an electromagnet keeps its force when the electricity goes off?
Check out how the magnetic field is produced - there's your answer.
What is the nail in an electromagnet?
The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.
