Question

Why the force is nil when a current carrying wire os parallel to magnetic field?

Answer 1

hey mate here is your ans -

When a conductor carrying a current is placed in a magnetic field, the conductor experiences a magnetic force.

The direction of this force is always right angles to the plane containing both the conductor and the magnetic field, and is predicted by Fleming’s Left-Hand Rule.

When the conductor is perpendicular to the magnetic field, the force will be maximum. When it is parallel to the magnetic field, the force will be zero.
