Question

A triangular conducting coil lies in a uniform magnetic field B which varies in time as shown in the graph of B (Tesla) versus t (seconds). At t = 1 s, the magnetic field is pointing out of the page. The triangle has height h = ?3 m, and the base of the triangle has length L = 2 m.

1) What is the magnitude of the induced EMF at t = 3.5s and what is the direction of the current (clockwise or counterclockwise) at this time?

A numerical and conceptual explaination would be nice

Explanation / Answer

emf = dflux/dt = A dB/dt
dB/dt = 2/1

so emf = sqrt(3)*2/2 * 2= 3.46 V

flux is decreasing so Binduced will be into the page
so current is clockwise
