The coefficient of coupling between two air coils depends upon factors such as the distance between the coils, the number of turns in each coil, the cross-sectional area of the coils, and the orientation of the coils with respect to each other. It also depends on the permeability of the medium between the coils and the relative alignment of the magnetic fields generated by each coil.

The coefficient of coupling between two air core coils depends on?
The coefficient of coupling between two air core coils depends on factors such as the physical distance between the coils, the number of turns in each coil, and the alignment of the coils relative to each other. It also depends on the relative orientation of the magnetic fields generated by each coil.
What is the factors on which the induced EMF in a coil rotating in a uniform magnetic field depends?
The induced EMF in a coil rotating in a uniform magnetic field depends on the strength of the magnetic field, the number of turns in the coil, the area of the coil, the speed of rotation, and the angle between the magnetic field and the plane of the coil.
What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
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.
Why the primary coil and the secondary coil of a physical transformer wrapped on each other?
Close approximation of the primary and secondary coils makes for an efficient transformer. It is the rise and fall of the magnetic field that surrounds the wire in the primary that induces a current to flow in the secondary. The closer the wire producing the magnetic field is to the conductor being cut by the magnetic field (induction) the better the secondary output.

The coefficient of coupling between two air core coils depends on factors such as the physical distance between the coils, the number of turns in each coil, and the alignment of the coils relative to each other. It also depends on the relative orientation of the magnetic fields generated by each coil.
What is Coefficient of coupling?
It is a measure of how close is a coupling between two coils it gives an idea of wat portion of the flux produced by one coil links with the other coil
What is the relationship between frequency and the size of a transformer?
Basically the characteristics of a transformer depends on the impedance(resistance) and on the coupling of its primary and secondary coils. The impedance of a coil depends on the frequency, as the frequency increases you need less volume of iron core and less number of turns in the coil for a given impedance, then reducing the size of the transformer.
What are the minimum amount of winding of coil for inductive coupling to take place between two metal coils?
Not even a single turn, just having two wires "near" each other will cause some inductive coupling between them. This is one of the causes of "crosstalk" that causes signal to appear in weakened form on wires they don't belong on (the other cause is capacitive coupling, which is also present between any two wires "near" each other).The real matter is how much coupling you want (or can tolerate, if you don't want coupling).
What is the factors on which the induced EMF in a coil rotating in a uniform magnetic field depends?
The induced EMF in a coil rotating in a uniform magnetic field depends on the strength of the magnetic field, the number of turns in the coil, the area of the coil, the speed of rotation, and the angle between the magnetic field and the plane of the coil.
What is the difference between a secondary and primary coil?
The primary coil is the one with voltage applied, or the 'input'. The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'. In a step up transformer, the secondary coil voltage is higher than the primary. In a step down transformer, the secondary coil voltage is lower than the primary. In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).
What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
How many hours or minutes can a coil burn?
It depends on the size of the coil and the burn rate.
Link coupling is used in r-f amplifiers to?
Link coupling is used to transfer energy between two r-f circuits which for whatever reason cannot be located near to each other. The method used in link coupling is a wire loop which stretches between the two stages, terminating at each end in a coil of few turns. At the output of the first stage, this wire loop will act as a step-down transformer, and at the input of the next stage it will act as a step-up transformer. To work in this manner the loop terminations must be positioned next to the inductor of the r-f tank circuit.
What is the difference between helical spring and coil spring?
is helical coil and coil spring are the same
What is the difference between inductive coupling and capacitive coupling?
A capacitor is a device that resists a change in voltage, proportional to current and inversely proportional to capacitance. dv/dt = i/c An inductor is a device that resists a change in current, proportional to voltage and inversely proportional to inductance. di/dt = v/l In an AC circuit with capacitive loading, the current waveform will lead the voltage waveform; while with inductive loading, the current waveform will lag the voltage waveform.
What is the relationship between the speed of the magnet as it travels through the coil and the amplitude of the voltage produced from coil?
The voltage would depend on the speed of the magnet. It also depends on other factors, e.g. the angle between the magnetic field lines and the movement, and the strength of the magnetic field at that point.
