Study Notes
Electromagnetic Induction
- Discovered by Michael Faraday in 1831
- Described mathematically by James Clerk Maxwell as Faraday’s law of induction
- A current is produced due to voltage (electromotive force) being generated by a changing magnetic field
- Two ways to generate this:
- Placing a conductor in a moving magnetic field (when using an AC power source)
- Constantly moving a conductor in a stationary magnetic field
- Experimentally demonstrated by Michael Faraday:
- A conducting wire was attached to a device to measure voltage
- A bar magnet was moved through the coil of wire
- The voltage detector measured voltage in the circuit
