What devices use electromagnetic induction?

What are the principles of electromagnetic induction?

  • The principle of electromagnetic induction is used in electronic components such as inductors and transformers. Electromagnetic induction is the basis of all types of electric generators and motors used to generate electricity from motion and motion from electricity.

What is a self excited induction generator?

  • An induction generator usually draws its excitation power from an electrical grid. Because of this, induction generators cannot usually " black start " a de-energized distribution system. Sometimes, however, they are self-excited by using phase-correcting capacitors.

What is induced EMF and induced current?

  • Lenz's law states that when an EMF is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced EMF is such, that it produces an induced current whose magnetic field opposes the initial changing magnetic field which produced it
