Inductance is the ability to store energy in the form of a magnetic field.
It is measured in henry and is denoted by the letter ‘L’.
An inductor is a conductive component that is designed to generate a strong magnetic field because a stronger magnetic field corresponds to higher inductance.
The symbol “L” was chosen to represent “inductance” in honor of the physicist Heinrich Lenz, who proposed Lenz's law, a modification of Faraday's law of electromagnetic induction. The letter ‘L’ is the initial from his last name.
