Answer 1

$B = B_{o} s i n (w t)$
$\frac{d B}{d t} = B_{o} w c o s (w t)$
at $t = \frac{π}{3 ω}$
$\frac{d B}{d t} = B_{o} w / 2$
The magnetic field is increasing.
According to Lenz's law, the current is induced to resist the change in magnetic field.
Hence According to right hand law current is in anticlockwise direction.

Answer 2

B = B_{o} s i n (w t)

\frac{d B}{d t} = B_{o} w c o s (w t)

at

t = \frac{π}{3 ω}

\frac{d B}{d t} = B_{o} w / 2

The magnetic field is increasing.
According to Lenz's law, the current is induced to resist the change in magnetic field.
Hence According to right hand law current is in anticlockwise direction.

Direction of current in the loop at $t = \frac{π}{3 ω}$ :

clockwise

anticlockwise

no current will flow at that time

cannot be determined

Figure shows a conducting loop placed near a long straight wire carrying a current $i$ as shown. If the current increases continuously, then the direction of the induced current in the loop is clockwise.

True or false?

Two circular loops $P$ and $Q$ are concentric and coplanar as shown in figure. The loop $Q$ is smaller than $P$ . If the current $I_{1}$ flowing in loop is decreasing with time, then the current $I_{2}$ in the loop $Q$
