A square coil of 50 turns and area

0.040\,\text{m}^2

is placed in a region where the magnetic field (normal to the plane of the coil) varies with time as

B = 0.30\sin(100\pi t)\,\text{T}

. What is the magnitude of the induced EMF in the coil at

t = 0.025\,\text{s}

? (a)

-1.88\,\text{V}

(b)

1.88\,\text{V}

(c)

0\,\text{V}

(d)

18.8\,\text{V}
