Mutual inductance is where two electrically separate coils of wire are either close to each other or share the same core. An alternating current flowing in one of the coils will 'induce' a current to flow in the other coil. For example by using coils wound with wire of the correct length and thickness, a transformer fed by mains electricity can by mutual inductance, produce a lower voltage to power your PC or radio.
CommentMutual inductance occurs when a changing current (a.c. or d.c.) flowing in one coil induces a voltage (not a current!) into a second coil.

What is mutual induced emf?
The property of one coil due to which it oposses the change of current in the other coil is called mutual inductance b\w two coil.
How do you measure inductance?
You can use a LCR (Inductance, Capacitance, Resistance) meter if you can find one.
What is the inductance of a circuit containing two 10 mh inductors connected in parallel?
Inductance in parallel is the reciprocal of the sum of the reciprocals of the individual inductance's. LPARALLEL = 1 / SummationI=1toN (1 / LI)
What is parasitic inductance of capacitor?
A: PARASITIC means like a parasite is there to offset the actual circuitry it can be inductance and/or capacitance A capacitor is usually wound in a coil this coil if frequency is hi enough will behave as a small coil has been added to the circuit. Hi frequency PWM capacitors have indeed four lead to reduce not eliminate this inductance
Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.
What is an example of mutual inductance?
A transformer because, to work, it must use mutual inductance between its separate windings.
What is the meaning of mutual inductance as transformer works on the principle of mutual inductance?
Mutual inductance describes the process by which a changing current in one coil, creates a changing magnetic flux which, when it links with a second coil, induces a changing voltage into that coil.
What are two types of EMF induced in a double wound transformer?
1. self- induction2. mutual- induction
What two factors affect the mutual inductance of two coils?
The mutual inductance of two coils is primarily affected by the number of turns in each coil and the relative positioning of the coils. Increasing the number of turns in either coil will increase mutual inductance, while placing the coils closer together will also increase mutual inductance as more magnetic flux is coupled between them.
What is inductance and types of inductance?
inductor is a electronic component that resist a change in the flow of current inductance is that property of inductor.
A common application of mutual inductance is found in a device called a?
Dildo
What principle emf induces in secondary winding of transformer?
mutual inductance
What factors determine the mutual inductance in a two coil system?
The mutual inductance in a two coil system is determined by the number of turns in each coil, the area of overlap between the coils, and the relative orientation of the coils.
Which bridge is used to find mutual inductance?
heavy side campbell bridge
Theory of coupled circuit?
Mutual inductance is the basic theory of the coupled circuits.
What is mutual coupling in transformer?
It stands for how does the primary and secondary winding magnetic fields connected firmly without much of leakage flux.
Is the mutual inductance of a transformer is constant under all operating conditions?
The mutual inductance is defined as the voltage induced in one winding when the current in the other winding changes by one amp per second. In an AC system it is the open-circuit induced voltage in the secondary divided by 2 x pi x frequency times the current in the primary. The mutual inductance is determined by the size and shape of the transformer. However if the transformer is operated at more than the rated flux-density of the magnetic core material, the mutual inductance falls (for normal laminated iron cores the maximum flux density is 1 Weber per square metre).
