what is the value of e.m.f acting upon charged point particle situated at the centre of a circular coil carrying a changing current
Inductance at the centre of a circular coil is a measure of the ability of the coil to store energy in the form of a magnetic field when an electric current passes through it. It is commonly denoted by the symbol L and is measured in units of henries (H).
Inductance at the centre of a circular coil 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 coil, A is the cross-sectional area of the coil, and l is the length of the coil.
The inductance at the centre of a circular coil is affected by the number of turns in the coil, the cross-sectional area of the coil, the permeability of the material inside the coil, and the distance between the turns of the coil. It also depends on the presence of any nearby magnetic materials or external magnetic fields.
Inductance at the centre of a circular coil can cause an opposition to changes in current, known as inductive reactance. This can lead to delays in the flow of current and can also affect the frequency response of the circuit. Inductance is an important factor in the design and functioning of many electrical devices.
Inductance at the centre of a circular coil has many practical applications, such as in transformers, motors, generators, and inductors. It is also used in wireless charging, radio frequency circuits, and electromagnetic compatibility testing. Inductance is a fundamental concept in the study of electromagnetism and is essential in the functioning of many modern technologies.
