Self inductance is the property of a circuit element that causes it to generate an electromotive force when the current through it changes. Self flux is the magnetic flux produced by the current flowing through the circuit element.
Self inductance and self flux are directly related to each other. The amount of self inductance is proportional to the amount of self flux, and both are determined by the geometry and material properties of the circuit element.
Self inductance refers to the production of an electromotive force in a circuit element due to the change in current through it, while mutual inductance refers to the production of an electromotive force in a nearby circuit element due to the change in current in the first element.
Self inductance and self flux can cause a delay in the response of a circuit to changes in current, known as inductive reactance. This can affect the overall impedance of the circuit and can also lead to energy being stored in the circuit element.
Self inductance is typically measured using an inductance meter or by observing the response of the circuit to a known change in current. It can also be calculated using the geometry and material properties of the circuit element.
