A long straight wire is carrying current I in +z direction. The x-y plane contains a closed circular loop carrying current I₂ and not encircling the straight wire. The force on the loop will be

Options

  1. A₀ /₁ /₀ / 2
  2. B₀ I₁ I₂ / 4
  3. Czero
  4. Ddepends on the distance of the centre of the loop from the wire

Correct answer

D. depends on the distance of the centre of the loop from the wire

Step-by-step solution

Situation is shown in the figure given below Thus, the force depends on the distance of the centre of the loop from the wire.
