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.
Relation between self inductance and relative permeability?
Self inductance is a property of a coil that depends on the geometry and number of turns of the coil. The relative permeability of a material is a measure of how easily it can be magnetized. The self inductance of a coil can be affected by the relative permeability of the material in the core of the coil, as a higher relative permeability can increase the magnetic field and thus the inductance.
How can I calculate the coil's self-inductance?
To calculate a coil's self-inductance, you can use the formula L ( N A) / l, where L is the self-inductance, is the permeability of free space, is the relative permeability of the core material, N is the number of turns in the coil, A is the cross-sectional area of the coil, and l is the length of the coil.
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 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 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.
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.
How might you reduce the inductance of an antenna coil?
To reduce the inductance of an antenna coil, you can decrease the number of turns in the coil, as inductance is proportional to the square of the number of turns. Additionally, using a smaller core diameter or increasing the spacing between turns can also lower inductance. Employing materials with lower permeability for the core can further contribute to reducing inductance. Finally, adjusting the coil's shape to be more elongated can help achieve the desired inductance reduction.
How do you calculate th inductance of a coil?
The inductance of a coil can be calculated using the formula ( L = \frac{N^2 \cdot \mu \cdot A}{l} ), where ( L ) is the inductance in henries, ( N ) is the number of turns in the coil, ( \mu ) is the permeability of the core material (in henries per meter), ( A ) is the cross-sectional area of the coil (in square meters), and ( l ) is the length of the coil (in meters). Alternatively, for air-core coils, you can use ( L = \frac{\mu_0 \cdot N^2 \cdot A}{l} ), where ( \mu_0 ) is the permeability of free space.
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.
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.
