Answer:
The process described, where an induced electromotive force (emf) is produced in a coil due to a change in current flowing through the same coil, is known as “self-induction”. Self-induction occurs when the magnetic field around a conductor (in this case, the coil) changes, inducing an emf in the coil itself according to Faraday’s law of electromagnetic induction. This phenomenon is a fundamental concept in electromagnetism and plays a crucial role in the operation of electrical devices such as inductors and transformers. When the current in the coil changes, the magnetic field around the coil changes as well, resulting in the generation of an induced emf that opposes the change in current. This self-induced emf is proportional to the rate of change of current and the number of turns in the coil, as described by the formula \epsilon = -L \frac{di}{dt} , where ( \epsilon ) is the induced emf, ( L ) is the inductance of the coil, ( di ) is the change in current, and ( dt ) is the change in time.
