Question

In the figure shown below each battery has e m f = 5 V . Then the magnetic field at P is, zero, 10 μ 0 R 1 ( 4 π ) ( . 2 ), 20 μ 0 ( R 1 ⁡ + R 2 ⁡ ) ( . 8 π ), none of these

In both the loop ∑ V = 0 Therefore I n e t = 0 since the current in both the loops is zero, the field at the point P will be zero.
