What is a magnetic field? A magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic.

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged …

Magnetic fields create force on moving charges. The force will accelerate the charge, changing its direction of velocity (ie. deflecting it).

A person pulls the wire with constant velocity through the magnetic field. As they do so, they have to apply a force. The constant magnetic field can’t do work by itself (otherwise its strength …

Learn what magnetic flux is, how to calculate it, and how it relates to Faraday's law.

So in short today we represent the magnetic field by drawing imaginary lines called the magnetic field lines. These field lines tell us in what direction the north pole of the tiny magnet points.

An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the …

The electric field E → is a vector quantity that exists at every point in space. The electric field at a location indicates the force that would act on a unit positive test charge if placed at that location.
