This section lists units commonly used in electricity and magnetism along with commonly used unit prefixes.

It expresses the effectiveness of a given device. When two circuits carrying time-varying currents are close to one another, the magnetic flux through each circuit varies because of the changing current in the other circuit. Consequently, an emf is induced in each circuit by the changing current in the other. This type of emf is therefore called a mutually induced emf, and the phenomenon is

For the capacitor of Figure 3.3.1 the curl of →H near the feed wires is associated only with →J (or I), whereas between the capacitor plates the curl of \(\…
