Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be “induced” in the coil. No matter how the change is produced, the voltage will be generated. This is made clear by Faraday’s Law.
Faraday’s first law of electrolysis states that
| The amount of substance liberated at an electrode is directly proportional to the quantity of electricity passed. |
Faraday’s second law of electrolysis states that if the same amount of electricity is passed through different electrolytes, the masses of ions deposited at the electrodes are directly proportional to their chemical equivalents.
