![]() ![]() Electric dipole fields obey an inverse cubed law, as does the magnetic field. Where μ₀=4π × 10−7 H/m is the magnetic constant, N is the number of turns, I is current, and L is the solenoid length.Ī magnetic field is an electric field created by a helical distribution of electric dipoles. ![]() The magnetic field (magnetic flux density is another name) B of a long solenoid in the air without a ferromagnetic core is measured using the formula below: In the automobile starter solenoid, for example, which is used as a starter relay to supply current to the starter motor and to shift the starter pinion of the starter motor into engagement with the engine flywheel, solenoids with ferromagnetic cores are most commonly used to transform electrical energy into linear motion. It produces a uniform magnetic field when an electric current passes through a solenoid. A solenoid with a length that is considerably greater than its diameter is a tightly woven coil.
