You are designing a generator with a maximum emf 8.0 v. if the generator coil has 200 turns and a cross-sectional area of 0.030 m2, what would be the frequency of the generator in a magnetic field of 0.030 t?

7.1 Hz

Explanation:

In a generator, the maximum induced emf is given by

where

N is the number of turns in the coil

A is the area of the coil

B is the magnetic field strength

f is the frequency

In this problem, we have

N = 200

B = 0.030 T

So we can re-arrange the equation to find the frequency of the generator:

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
