2. Electromagnetic induction - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_induction

   Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

3. Faraday's law of induction - Wikipedia

   en.wikipedia.org/wiki/Faraday's_law_of_induction

   Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...

4. FBI mnemonics - Wikipedia

   en.wikipedia.org/wiki/FBI_mnemonics

   The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.

5. Electrostatic induction - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_induction

   Gold-leaf electroscope, showing induction (labelled polarity of charges), before the terminal is grounded. Using an electroscope to show electrostatic induction. The device has leaves/needle that become charged when introducing a charged rod to it. The leaves bend the leave/needle, and the stronger the static introduced, the more bending occurs.
