Question

In which of the following cases a straight current-carrying conductor does not experience a force?

Options:

A . The direction of the current is perpendicular to the magnetic field.

B . The direction of the current is parallel to the magnetic field.

C . The angle between the conductor and the magnetic field is 60∘.

D . The angle between the conductor and the magnetic field is 45∘.

Answer: Option B
:
B
When a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor. The direction of this force is perpendicular to both the direction of current as well as the direction of the magnetic field(Fleming's left-hand rule).
The conductor will not experience a force if the angle between the current and the magnetic field is
