Q10:

Question for Assertion & Reason Type Questions: Magnetic Effects of Current
Try yourself: Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : A current carrying conductor experiences a force in a magnetic field.

Reason : The force acting on a current carrying conductor in a magnetic field is due to interaction between the magnetic field produced by the current carrying conductor and the external magnetic field in which the conductor is placed.
