Assertion (A) : The deflection of a compass needle placed near a current carrying wire decreases when the magnitude of an electric current in the wire is increased. Reason (R) : Strength of the magnetic field at a point due to a current carrying conductor increases on increasing the current in the conductor.
  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  3. (A) is true, but (R) is false.
  4. (A) is false, but (R) is true.
