Two circular coils P and Q are fixed coaxially and carry currents I₁ and I₂ respectively

Select all that apply

• Option A

  if I₂ = 0 and P moves towards Q, a current in the same direction as I₁ is induced in Q

• Option B

  if I₁ = 0 and Q moves towards P, a current in the opposite direction to that of I₂ is induced in P

• Option C

  when I₁ ≠ 0 and I₂ ≠ 0 are in the same direction then the two coils tend to move apart

• Option D

  when I₁ ≠ 0 and I₂ ≠ 0 are in opposite directions then the coils tends to move apart
