Emf induction coil

WebWell, the technology is based on electromagnetic induction. Discovered by Micheal Faraday more than 200 years ago. The basic idea is that if you take a wire and move it up or down inside a magnetic field, it induces an electric current. So, all we have to do is attach a coil of wire to these giant turbines, and place them inside a magnetic field. WebAug 6, 2024 · The inductance of a coil refers to the electrical property the inductive coil has to oppose any change in the current flowing through it. It therfore follows that inductance is only present in an electric circuit when the current is changing. Inductors generate a self-induced emf within themselves as a result of their changing magnetic field.
