Formula for induced current

WebSep 12, 2024 · A current I is flowing along the wire of the solenoid. The number of turns per unit length is N / L; therefore, the number of turns in an infinitesimal length dy are ( N / L) dy turns. This produces a current (12.7.1) d I = N I L d y. We first calculate the magnetic field at the point P of Figure 12.7. 1. WebIt is the most convenient method to determine the direction of the induced current. It states that the direction of an induced current is always such as to oppose the change in the circuit or the magnetic field that produces it. …
