Definitions for "magnetic induction"
Same as magnetic field strength.
Physics- the generation of an electrical current in a conductor caused by motion between the conductor and external magnetic fields. This is how hydroelectric power generators work-- pressurized steam is passed through a fan, around whose axle is a large magnet. Stationary electrical conductors surround the magnet; as the fan turns, the magnetic field changes in relation to the conductors, and induces a current. The opposite is also true-- this is how a motor works.
Generating a voltage in a circuit by the creation of relative motion between a magnetic field and the circuit. The relative motion can be the result of physical movement or the rise and fall of a magnetic field created by a changing current.
The process that makes a substance magnetic (temporarily or permanently).
