II. Understanding Coil Voltage
A. Explanation of Coil Voltage in Electromagnetic Devices
Coil voltage is generated through electromagnetic induction, a principle discovered by Michael Faraday in the 19th century. When a conductor, such as a wire coil, is placed in a changing magnetic field, an electromotive force (EMF) is induced across the coil. This induced voltage is proportional to the rate of change of the magnetic field and the number of turns in the coil. The ability to control and manipulate coil voltage is vital for the operation of various devices, including motors, generators, and solenoids.
