The resultant magnetic field at point 'P' situated midway between two parallel wires (placed horizontally) each carrying a steady current I is. CBSE 2023 Science Class 10 Question Paper Solved.
  1. in the same direction as the current in the wires.
  2. in the vertically upward direction.
  3. zero
  4. in the vertically downward direction.

zero

Reason — The magnetic fields produced at the midpoint P, by the currents flowing in the same direction in the two parallel wires will be equal in magnitude but opposite in direction.

Hence, the resultant magnetic field at P will be zero.
