A square loop of side

15 \mathrm{~cm}

being moved towards right at a constant speed of 2

\mathrm{cm} / \mathrm{s}

as shown in figure. The front edge enters the

50 \mathrm{~cm}

wide magnetic field at

t=

0 . The value of induced emf in the loop at

t=10 \mathrm{~s}

will be :

A square loop of side 15 ~cm being moved towards right at a constant speed of 2 cm / s as shown in figure. The front

Options

A $0.3 \mathrm{mV}$
Bzero
C $4.5 \mathrm{mV}$
D $3 \mathrm{mV}$

Correct answer

B. zero

Step-by-step solution

\mathrm{t}=10 \mathrm{sec}

complete loop is in magnetic field therefore no change in flux A square loop of side 15 ~cm being moved towards right at a constant speed of 2 cm / s as shown in figure. The front

\mathrm{e}=\frac{\mathrm{d} \phi}{\mathrm{dt}}=0

\mathrm{e}=0

for complete loop
