Q. A square coil $ABCD$ lying in $x - y$ plane with it’s centre at origin. A long straight wire passing through origin carries a current $i = 2t$ in negative $z$-direction. The induced current in the coil is
A) Clockwise
B) Anticlockwise
C) Alternating
D) Zero
Explanation
(d) Magnetic lines are tangential to the coil as shown in figure. Thus net magnetic flux passing through the coil is always zero or the induced current will be zero
