the link between electricity and magnetism.
In: Physics
Both electric and magnetic forces are part of a single phenomenon called electromagnetism. Electricity is the flow of charged particles through a material, this movement of charges generates a magnetic field. If you change the movement (eg changing the current) then you’ll also change the magnetic field. These magnetic fields also act on charged particles, magnetic fields accelerate moving charges. This means that if you have a load of charges moving through a magnetic field they will feel a force applied to them. However it turns out that instead of having the charges moving you can also move or vary the magnetic field, a changing magnetic field will apply a force to charged particles like electrons in a wire.
This means that a changing magnetic field can induce an electric potential (electricity) and a changing electric potential will induce a magnetic field.
