The cores for Tesla coil secondary coils are usually plastic, and smaller ones may be cardboard, and therefore count as air core coils. And if you're not familiar with the notation 1.26x10-6, it's just another way of writing 0.00000126. The area includes part of the coil, as shown in the diagram above.

How can I calculate the inductance of the primary of a ...

Ohm resistors (resistance) in the secondary create active currents both in the primary and in the secondary. Coils in the other hand create imaginary current (current is late by 90 degree from voltage) so there is no way that adding load in the secondary is effecting the inductance of the primary, only the Ohmic resistance.

Mutual Inductance of Two Adjacent Inductive Coils

When the coefficient of coupling, k is equal to 1, (unity) such that all the lines of flux of one coil cuts all of the turns of the second coil, that is the two coils are tightly coupled together, the resulting mutual inductance will be equal to the geometric mean of the two individual inductances of the coils. Also when the inductances of the two coils are the same and equal, L 1 is equal to ...

Inductive coupling - Wikipedia

Unintentional inductive coupling can cause signals from one circuit to be induced into a nearby circuit, this is called cross-talk, and is a form of electromagnetic interference. An inductively coupled transponder consists of a solid state transceiver chip connected to a large coil that functions as an antenna .

Application of the rated voltage is the most basic requirement for accurate relay operation. Although the relay will work if the voltage applied exceeds the pick-up voltage, it is required that only the rated voltage be applied to the coil out of consideration for changes in coil resistance, etc., due to differences in power supply type, voltage fluctuations, and rises in temperature.

Analysis of the Coupling Coefficient in Inductive Energy ...

The coupling coefficient is dependent on how much of the magnetic field flux is encircled by the secondary coil, being higher if a high density of lines is projected through the secondary coil. The amount of magnetic field lines diverging from the secondary coil can be seen as a field leakage, reducing the coupling between the two coils.
