Since a coil contains numerous loops, more of the conductor is affectedÊ by the magnetic field. An increase in permeability of the core results in an increase in the inductance of the coil.

How does the diameter of wire coil affect the amount of electricity?
The diameter of the coil affects the amount of electricity as longer the coil longer the electricity.
What is an electrical circuit that produces a magnetic field?
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.
What is a non permanent magnet?
An electromagnet (a coil around a soft iron core) will only be magnetic when current changes in the coil and so is not permanent.
What condition will sinusoidal voltage be generated in a coil of wire that rotates in a magnetic field?
a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
How many fathoms in a coil of rope?
A fathom is six feet in length. Rope is usually sold in 100 foot coils. As such, a single coil of rope has 16 2/3 fathoms. This can vary, of course, depending on if the coil of rope is really 100 feet, or some other amount.
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.
Why air coil with soft iron core inductance is greater then air coil laminated steel core?
Soft iron has a greater permeability than steel. BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.
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.
What is mutual conduction in magnets?
Mutual inductance is where the magnetic field generated by a coil of wire induces voltage in an adjacent coil of wire. A transformer is a device constructed of two or more coils in close proximity to each other, with the express purpose of creating a condition of mutual inductance between the coils.
What are the Example each for self induced and mutually induced emf?
if an emf is induced in a coil due to the current flowing through itself is called SELF INDUCTANCE. on the other hand if an emf is induced on another coil due to the current flowing through the previous coil then it is called MUTUAL INDUCTANCE. suppose there are two coils A and B a current is flowing through A. now if the flux produced due to this current induce an emf on the same coil A, then it is SELF INDUCTANCE, and if it produce emf on B, then it is MUTUAL INDUCTANCE due to coil A.
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.
What is meant by mutual inductance?
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 two things is the value of inductance affected by?
There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil): 1. Number of turns in the coil (N) 2. Length of coil (l) 3. Cross sectional area of coil (A) 4. Material (nature, or permeability) of coil: u(Greek meu) Inductance, L=(N^2 . u.A)/l
When you will get maximum inductance in the copper wire?
The inductance of a wire or coil is upon the length of wire and the permeability of the core material, if not air.To maximise inductance, use more wire (and wind into a solenoid shape).To maximise the inductance for a given volume, ensure that the winding cross-section is approximately square (i.e winding thickness = winding height).Lastly, to maximise the inductance of a square assembly, use a core with higher permeability, such as iron for power frequencies, or powdered iron or ferrite for higher frequencies.
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is inductance comparsion bridge and its application?
It is used to measure the inductance of a coil of unknown inductance.
