	Inductance - Wikipedia, the free encyclopedia
		Inductance (or electric inductance) is a measure of the amount of magnetic flux produced for a given electric current.
		The SI unit of inductance is the henry (symbol: H).
		The symbol L is used for inductance, in honour of the physicist Heinrich Lenz.

	Mutual Inductance
		The fact that a change in the current of one coil affects the current and voltage in the second coil is quantified in the property called mutual inductance.
		The induced emf in coil 1 is due to self inductance L. The mutual inductance M can be defined as the proportionalitiy between the emf generated in coil 2 to the change in current in coil 1 which produced it.
		The mutual inductance appears in the circuit equations for both the primary and secondary circuits of the transformer.

	Rare-Earth Magnets - Mutual Inductance
		It is actually intended as a precision standard unit for mutual inductance, but for the purposes of illustrating what the essence of a transformer is, it will suffice.
		The only applications for mutual inductance in a DC system is where some means is available to switch power on and off to the coil (thus creating a pulsing DC voltage), the induced voltage peaking at every pulse.
		Mutual inductance is where the magnetic field generated by a coil of wire induces voltage in an adjacent coil of wire.

	Inductance
		Mutual inductance is when two coils are located so that the magnetic flux from one coil links with the turns of another coil.
		When inductance are not coupled (far enough apart to not influence each other) and connected in series the total inductance is the sum of the individual inductances.
		When two mutually coupled coils are connected in series the total inductance is affected by their fields either series-aiding or series-opposing each other.

	Mutual inductance NMR RF coil matching device - Patent 4638253
		The capacitance and inductance associated with the NMR RF coil are shown as lumped elements C.sub.2 and L.sub.2, respectively, with L.sub.2 and L.sub.1 being coupled by a mutual inductance designated "M".
		This relationship holds true when the capacitors and inductors in the coil are at resonance, as would be the case in normal operation, wherein the matching and RF coils are designed to resonate at the Larmor frequency of the nuclei of interest and the RF source frequency is equal to the desired resonant frequency.
		Rotation of the matching coil has the effect of changing the mutual inductance M, but has very little effect on the self-inductance L.sub.1 of the matching coil due to the fact that the length and the geometry thereof do not change as a result of the rotating motion.

		This effect is called mutual inductance: the induction of a voltage in one coil in response to a change in current in the other coil.
		With lower winding inductances, the primary and secondary voltages are closer to being equal, but the primary and secondary currents are not.
		Mutual inductance is where the magnetic flux of two or more inductors are "linked" so that voltage is induced in one coil proportional to the rate-of-change of current in another.

	Inductance (Site not responding. Last check: 2007-10-24)
		It is important to keep separate the two kinds of inductance, mutual inductance and self inductance.
		The mutual inductance between two circuits is defined to be the magnetic flux produced in circuit 1 by the current in circuit 2 divided by the current in circuit 2; or to be the flux produced in circuit 2 by the current in circuit 1 divided by the current in circuit 1:
		Like the capacitance and the resistance, the inductance of a coil depends only on its geometry and on the materials of which it is made.

	Title page for ETD etd-08102000-16110018
		To describe the effects of mutual coupling between phases, a set of voltage and torque equations is newly derived for the two-phase excitation.
		It is shown that the mutual inductance of two adjacent phases partly contributes to generate the electromagnetic torque and introduces coupling between two adjacent phases in the current or flux linkage control loop, which has been neglected in the single-phase excitation.
		The dynamics of the current or flux linkage loop are coupled and nonlinear due to the mutual inductance between two adjacent phases and the time varying nature of inductance.

		Inductance extraction is becoming critical not only in communications design, but also in pure digital designs.
		Further studies on a clock net in the presence of a power and ground grid indicate a 52% change in delay (86ps versus 131ps) and a 111% variation in worst case slew (9ps versus 19ps) when considering not only loop inductance, but also mutual inductance.

	The properties of mutual inductance standards at telephonic frequencies (Site not responding. Last check: 2007-10-24)
		It is well known that when a mutual inductance carries alternating current, the value of the effective mutual inductance varies with the frequency, and further that the secondary P.D. is not exactly in quadrature with the primary current.
		Thus certain frequency corrections are introduced into all alternating-current bridges in which a mutual inductance standard is used.

		A direct comparison of the units of inductance derived in the two laboratories has been made, using a third Campbell standard whose value was determined electrically.
		Despite the good agreement, the trend today in national laboratories is to substitute calculated capacitance for calculated inductance as the primary basis for the units of reactance and resistance.

		Re: could you have mutual inductance between two superconducting coils?
		Mutual inductance results from coils sharing some (in the limit, all) of the same magnetic lines of force.
		The area within the coils is not superconducting, and that's why mutual inductance is allowed.
