Question

Estimate the given parts of following question:

Question: A uniform magnetic field is at right angles to the plane of a wire loop. The field decreases by 0.15Tin 1.0 x 10³ s and the magnitude of the average emf induced in the loop is 85V.

Part I: What is the area of the loop?

Part II: What would be the value of the average induced emf if the field change was the same but took twice as long to decrease?

Part III: What would be the value of the average induced emf if the field decrease was twice as much and it also took twice as long to change?
