| ASSERTION: A current carrying conductor experiences a force in a magnetic field. |
| REASON: The net charge on a current carrying conductor is zero. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
When a current carrying conductor having no net charge placed in a magnetic field, the free electrons of the conductor move towards the positive end of the conductor with same drift velocity, hence magnetic force acts on them. The positive ions of the conductor being stationary, do not experience any magnetic field.
