A car generator turns at 470 rpm when the engine is idling. Its 290-turn, 5.20 by 6.20 cm rectangular coil rotates in an adjustable magnetic field so that it can produce sufficient voltage even at low rpms. What is the field strength needed to produce a 23.0 V peak emf? (Discuss how this required field strength compares to those available in permanent and electromagnets.)
Step by Step Solution
There are 3 Steps involved in it
Step: 1
To determine the field strength needed to produce the peak EMF of the generator we can use Faradays ...
