- n. The property of an electric circuit by which a voltage is induced in it by a changing magnetic field.
- n. The quantity of the resulting electromagnetic flux divided by the current that produces it, measured in henries (SI symbol: H.)

- n. Capacity for induction; the coefficient of self-induction.
from The Century Dictionary and Cyclopedia
- n. Power of induction; specifically, the coefficient of self-induction. See induction, 6.
- n. It is the property of an electric current in a circuit (called the inducing circuit) of producing a magnetic field surrounding the circuit, which when changing induces an electromotive force in a circuit surrounded by this field or a part thereof (called the induced circuit). If the induced and the inducing circuit are the same, the property is called self-inductance, otherwise mutual inductance. Unit inductance is the number of lines of magnetic force produced by unit current in the inducing circuit and interlinked with the conductor of the induced circuit: 10 times this unit is the practical unit of inductance, called a henry.

Sorry, no etymologies found.
Yes, I can't remember why we didn't go up a bit in inductance; it was largely a trial and error business really.
The latter equation indicates that, in a current-carrying coil, an electromotive force is induced by the magnetic flux associated with the current in the coil; the magnitude of the electromotive force is proportional to the rate of current change DI/Dt. The proportionality factor is called inductance L (more precisely self-inductance).
The storage capacity for magnetic energy is called inductance of a coil.
Leakage inductance occurs when the magnetic flux does not fully couple to the secondary winding.
Resistance heater vs the inductance load of an A/C motor.

Also, I continually feared that performance was being degraded because the previous magnet was not turning off fast enough due to inductance effects in the coil.
Althouse and pals use "Henry" to mean a unit of inductance in which an induced electromotive force of one volt is produced when the current is varied at the rate of one ampere per second.
Regular “old fashioned” incandescent light bulbs (which are “Resistive” in nature and exhibit very little AC inductance or capacitance and therefore no phase shift), have an AC Power Factor very close to “1.0”; therefore Real and Apparent Power are virtually the same.
Most of the new “magnetic motor” devices work by exploiting previously unexplored aspects of magnetism and/or inductance.
