what is a difference between electromagnetic and magnetic force?

Answer 1

Magnetic force is stored magnetic energy, for example a magnet has constant positive and negative electrodes which are ever present. If you put them near metal they will always attract.

Electromagnetic force is generated magnetic energy. When voltage and current are applied this will create magnetism in the electromagnet making it attract to metals. When the power is turned off the magnetism will cease to exist.

A perfect example of electromagnetism is the magnetic cranes you see in wrecking yards. by simply dropping the magnet into a pile of old metals while charged it can pick up and move the scrap easily without having someone to tie the load. Then when they want to release it they just hit the button and it stops current flow through the magnet allowing it to release it's energy and the load. If they used a magnetic crane they could not drop the metals into the compactors.

Answer 2

Electromagnetic force is explained by Maxwell's equations. The principal is that magnetic force and electric force are intimately bounded together - neither can exist without the other. In an electromagnetic wave, the magnetic force is much less than the electric force but it is still there. Any piece of circuitry you can think of where there is an electric current there exists a magnetic field emanating from it and an electric field driving it. For this reason people tend to talk about the electromagnetic force and electromagnetic energy. As the two cannot be separated this is a sensible thing to do unless you specifically wish to analyse either the electric or the magnetic component of electromagnetism.

Answer 3

There is no real difference. Both forces are essentially the same.

Electromagnetic force in generated by an electric current that generates a magnetic field.

Magnetic force is generated in exactly the same way, but here the currents are microscopic. It is the flow of electrons around the nucleus in the atoms that generates the magnetic force.

The term electromagnetism is usually used when dealing with macroscopic streams of electricity and magnetism is a by-product (not necesseraly unwanted) of these electric currents.

Answer 4

Technically, the only difference is that magnetic force is only part of electromagnetic force, but the truth is that they both exist simultaneously, and the "lines of force" are just oriented in different directions. If there is electric force there is magnetic force, and vice versa.

Answer 5

magnetic force of attraction arises only due to impact of magnets..

electromagnetic field is mostly produced by producing varying electric or magnetic fields..(like both are involved)eg, AC(alternating current)generator.here,magnetic field is given through a strong horse shoe magnet and the coil within is rotated..
