II. Basic Principles of Inductance
A. Explanation of Inductance
Inductance is the property of an electrical conductor that opposes changes in current. When current flows through a coil of wire, it generates a magnetic field around it. If the current changes, the magnetic field also changes, inducing a voltage in the opposite direction according to Lenz's Law. This phenomenon is the basis of inductance.
B. Role of Magnetic Fields in Inductance
The magnetic field created by the current-carrying conductor is crucial for the operation of inductors.
