What causes electromagnetism?

Answer 1

This is a BIG QUESTION. There are four fundamental forces--Electromagnetism, gravity, the strong and weak atomic forces. These forces are what we were given when this universe was created. There could have been more forces, or fewer. But that's what we have. habeeb_rulz: addition: The electromagnetic force occurs because of the exchange of messenger particlescalled photons and w and z bosons (particles which make up sub atomic particles such as electrons and protons). The exchange of messenger particles between bodies acts to create the perceptual force which attracts or repels the two larger particles such as protons or electrons.

Answer 2

All electromagnetic force is generated by electrically charged particles and the motion of those particles. The basic law which describes this is Coulomb's Law. Electrical charge (positive or negative), the motion of that charge, and the distances between charged particles are the variables. In practice, because metal contains clouds of free electrons (which are electrically charged), most of the things that we use to affect electromagnetic force are made of metal.

Answer 3

The spinning of the electron causes a magnetic field.

When a group of electrons in a solid are made to have their spins oriented the same, then we have a permanent magnet.

When a current of electrons flows along a conductor, thy generate an electro magnetic field.

Answer 4

well, an electric force is caused by an electric charge, which is basically another way of saying that in a certain volume of space, where a field exists, a positive test charge will experience a force towards a negative object creating a field, and away from a positive charge creating a field, hence field lines move away from a positive charge, and towards a negative charge (its just convention). If an object has no negative or positive charge, and it passes through an electric field, it will not experience a force on it.

Now, there are two ways to create a magnetic field: one is when there is a flow of charge (an electron moving through space), or when current flows in a wire, around that wire will be a magnetic field.

The other type of magnetic field is to do with the way the atoms that make up a permanent magnet are arranged.

Answer 5

Charge causes magnetic and electric forces. F= qE + qvxB

Answer 6

Electromagnetic waves are caused by accelerating electric charges.

Answer 7

The change of atomic configuration.
