Magnetic Induction in Coils
Description
Magnetic induction in coils is demonstrated with inductive coils and a voltmeter. A rod magnet is inserted into or pulled away from the core of a coil to create a brief electromotive force, or emf, in the coil. The voltmeter measures the resulting voltage change.
The experiment also shows mutual ...

Transcript
Inductors -- typically in the form of coils -- are commonly used in many circuit applications. Their purpose is to store magnetic energy when a steady state current flows.
In a loop that forms a closed circuit, the changing magnetic field induces an electromotive force that drives the current. This phenomenon is called electromagnetic indu...
