Question

g In Example 31.1, Select one: a. Only this is correct. I. the induced magnitude emf is calculated by taking the absolute value of total B field change over the total time, multiplying the unchanged area, and number of loops. b. Only this is correct. II. the expected current would be zero, if the ends of the coil are not connected. Otherwise, the induced current would be the induced emf over the total resistance in the circuit. c. both I and II are correct. d. Both are wrong.

Answer 1

Check the explanation

Step-by-step explanation:

(31)

induced EMF depends on change in angle

`E=BA(d(cos\theta ))/(dt)`

Answer is option (b) i.e.,rotating the loop about an axis perpendicular to the field lines

(31) True

Induced emf.
`E=NAcos\theta(d(B))/(dt)`
