I wanted the proof how the equation of L is derived. :/nasu said:
Self inductance is a property of a circuit that describes its ability to generate an electromotive force (EMF) in response to a changing current in the circuit. It is measured in units of henries (H).
The self inductance of a circular loop of wire can be calculated using the formula L = μ0 * N^2 * A / l, where μ0 is the permeability of free space, N is the number of turns in the loop, A is the area of the loop, and l is the length of the loop.
The self inductance of a circular loop of wire is affected by the number of turns in the loop, the area of the loop, and the material the loop is made of. It is also affected by the presence of nearby magnetic fields.
Self inductance plays a crucial role in the behavior of circuits, particularly in the generation and suppression of EMF. It is also a major factor in determining the inductance of an inductor, which is used in many electronic devices.
Self inductance can be measured using an inductance meter or by using a circuit with known values of resistance and frequency. It can also be calculated using the formula mentioned in the second question.
