Question

when the magnetic field changes in a coil of wire, voltage in each loop of the coil is induced. what is the name of the voltage induced in a loop if the source of the magnetic field is the coil itself?

Answer 1

When the coil itself serves as the source of the magnetic field, self-induction refers to the voltage created in a loop.

What is Self-induction?

• A coil experiences an induced emf when the current in the coil varies because the magnetic flux that is related to the coil also changes. Self induction is the term for this phenomenon. The induced emf opposes the change in magnetic flux, according to Lenz's law.
• A circuit's self-inductance is used to describe how it responds to changes in its own current, whereas a second circuit's mutual inductance with regard to it defines how it responds to changes in its own current.
• Henry 'H', Weber/Ampere, or self-inductance is measured in this unit.
• The electromagnetic force that a coil experiences when the current flowing through a coil or conductor changes is known as self-induced EMF.
