Question

what are electromagnetuc induction using two coils

Answer 1

it is to use the device as a generator, thecoil can be spun, inducing a current in the coil. An AC (alternating current) generator utilizes Faraday's law ofinduction, spinning a coil at a constant rate in a magnetic field to induce an oscillating emf

Answer 2

in electromagnetic induction two coils are use to increase the production of electricity
