Henry, unit of either self-inductance or mutual inductance, abbreviated h (or hy), and named for the American physicist Joseph Henry.
For example, one metre of straight copper wire has a self-inductance on the order of one microhenry.
The self-inductance of a coil, or simply its inductance, may thus be thought of as electromagnetic inertia, a property that opposes changes both in currents and in magnetic fields.
Such a phenomenon is called self-induction, and the quotient of the induced electromotive force and the rate of change of the current is specified as self-inductance.
One henry is the value of self-inductance in a closed circuit or coil in which one volt is produced by a variation of the inducing current of one ampere per second.
Stator self-inductance L ss = 4.450.
The early motors were classified as motors with separate sequentially switched magnetic circuits (variable self-inductance) and motors with mutually coupled sequentially switched magnetic circuits (variable mutual inductance).
The coil was an element of a resonant RLC circuit with a self-inductance of 48 μH.
Calculation of self-inductance of such coils was also carried out and was compared with FE simulation.
