Hans Orsted first discovered that when an electric current was run through a wire and put close to a compass, the needle moved toward it. Although, he had no idea what that meant.
Michael Faraday, built on his work and found that when an electric current runs through a wire, a magnetic field is produced around the wire. He also found that an electric field is around a wire it produces an electric current. The direction of the current depends on which direction the field is going in. The faster you move the electric field the stronger the current.

Electrons are held in atoms by- A. Electromagnetic B. Friction C. Gravity D. The strong nuclear force?
Electromagnetic Force
What opposes the electromagnetic force in the nucleus of an atom?
The "strong nuclear force" does.
The effects of the electromagnetic force on two charged particles is that of?
The effects of the electromagnetic force on two charged particles is that of repulsion between the like charges.
How are magnetism and electricity the same?
electromagnetic force
What is the particle that mediates the electromagnetic force?
The photon.
Who discovered the principle electromagnetic induction?
Michael Faraday discovered Electromagnetic induction.
Who are the scientists that discovered the electromagnetic induction?
Michael Faraday discovered the electromagnetic induction in 1831
What do Mechanical and Electromagnetic have in common?
Motion. Physics. Electromagnetic force; gravitational force. eh?
Difference between electrostatic force and electromagnetic force?
electrostatic force is the force between the two opposite charges where as the electromagnetic force is movement of electrons
Force of pushing or pulling between magnetic poles?
This is the Electromagnetic force. (Technically, it's the Lorentz force, which is the force on a charge due to an electromagnetic field, but either will do.)
Photon does not have charge then how does it have electromagnetic field?
Well one way to look at it is that a photon IS an electromagnetic field. The photon is the gauge particle for the electromagnetic force. Without photons there would be no electromagnetic interaction force, and therefore no electromagnetic fields.
4 types of forces?
Gravity, electromagnetic, strong nuclear, weak nuclear.
What is the electromagnetic force transmitted by?
Electromagnetic force is transmitted by photons. Photons are a particle representing a quantum of light or other electromagnetic radiation. It carries energy proportional to the radiation frequency but has zero rest mass.Ê
Who discovered the principle of electromagnet induction?
Michael Faraday discovered Electromagnetic induction.
Electromagnetic force occurs when?
an electromagnetic field interacts with charged particles.
How is magnetic force discovered?
who discovered the magnetive force
How can you measure the mass of a photon?
One method is to determine the effectivity of the electromagnetic force over a distance. The electromagnetic force acts over an infinite distance and therefore the photon, the particle that mediates the electromagnetic force, is massless.
