## What causes electric field and magnetic field?

Electric fields are created by differences in voltage: the higher the voltage, the stronger will be the resultant field. Magnetic fields are created when electric current flows: the greater the current, the stronger the magnetic field. An electric field will exist even when there is no current flowing.

## What causes electric fields?

Electric fields are caused by electric charges, described by Gauss’s law, and time varying magnetic fields, described by Faraday’s law of induction. Together, these laws are enough to define the behavior of the electric field.

## What are magnetic fields caused by?

Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.

## How electric and magnetic fields are produced?

Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. … As current moves through a power line, it creates a magnetic field called an electromagnetic field.

## What causes the changing electric field and magnetic field in a charge?

Feedback loop

the electric and magnetic fields are generated by moving electric charges, the electric and magnetic fields interact with each other, the electric and magnetic fields produce forces on electric charges, the electric charges move in space.

## How are electricity and magnetism related?

Electricity and magnetism are two related phenomena produced by the electromagnetic force. Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current.

## What do electric forces and magnetic forces have in common?

Electric and magnetic forces are non-contact forces, which means objects exerting these forces on each other don’t need to be touching. The two types of forces are related; a moving magnet can make electrical charges move, cause an electric current, and in turn cause magnetism.
