Problem: The figure (Figure 1) shows the magnetic flux through a single-loop coil as a function of time.Part AWhat is the induced emf in the coil at t=0.050s?Part BWhat is the induced emf in the coil at t=0.15s?Part CWhat is the induced emf in the coil at t=0.50s?

FREE Expert Solution

Induced emf:

ε=-dϕdt'

This implies that the induced emf is the negative of the slope of the flux versus time graph. 

ε=-(ϕ2-ϕ1t2-t1)

Part A

At t = 0.05 s, the slope is:

ε=-(10-00.1-0)
