MCQ
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
  • ✓
    Zero
✓

Answer

Correct option: D.
Zero
d
(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.
