1Physics A law stating that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage.

Example sentencesExamples
Thus, by Faraday's law, which states that a changing magnetic flux induces an electrical field, a current is established in the wires which wrap the pickup magnet.
Faraday's Law of Induction...states that an induced electric field (E) is created by a changing magnetic flux density (dB/dt) with a polarity that opposes the changing magnetic field (-). The faster the flux density changes, the greater the induced electric field.
2Chemistry A law stating that the amount of any substance deposited or liberated during electrolysis is proportional to the quantity of electric charge passed and to the equivalent weight of the substance.
〔化〕法拉第定律
Example sentencesExamples
In 1909, about 80 years after the discovery of Faraday's law of electrolysis, a precise measurement of elementary charge was carried out by R. A. Millikan.
Since a zinc-air battery uses the oxygen in the atmosphere as the cathode material, students were able to confirm Faraday's law of electrolysis by measuring the volume of oxygen absorbed and reacting in the battery.
