A thin and infinitely long metal sheet of appreciable finite width b carrying current I (distributed uniformly through out of its cross section) parallel to its length is placed in an external magnetic field B_e parallel to its plane and perpendicular to the direction of current

Options

  1. AThe thin metal sheet experiences a mechanical pressure P = I ~B _ e h perpendicular to its face.
  2. BThe direction of the pressure does not change if the direction of current is reversed.
  3. CIn case the external magnetic field B_c is switched off, a magnetic field B= ₀ I 2 b is observed parallel to t
  4. DThe magnetic field produced in part (c) is B = 2 ₀ I b

Correct answer

C. In case the external magnetic field B_c is switched off, a magnetic field B= ₀ I 2 b is observed parallel to t
