In the figure, a conducting ring of certain,resistance is falling towards a current carrying straight long conductor. The ring and conductor are in the same plane. Then, the

Options

  1. Ainduced electric current is zero
  2. Binduced electric current is anti-clockwise
  3. Cinduced electric current is clockwise
  4. Dring will come to rest

Correct answer

C. induced electric current is clockwise

Step-by-step solution

Magnetic field around the current carrying straight long conductor. B= ₀ I 2 r where, r is distance from the conductor. Hence, magnetic field increases on moving towards the conductor. Since, metal ring is moving towards the conducting wire, hence flux linked with ring, increases continuously in the out of plane direction. Hence, the induced current produces a magnetic field into the plane of paper. Thus, induced current will produce in the clockwise direction.
