If a current-carrying wire is in a magnetic field, in what direction will a force be exerted on the wire?
2 answers:
Answer : Perpendicular to both the magnetic field and the current direction
Explanation :
If a current-carrying wire is in a magnetic field, the magnetic force exerted on the wire is given by :
.............(1)
Where
q is the electric charge
v is the velocity with which the particle is moving
B is the magnetic field
The direction of magnetic force is can be find by using right hand rule.
From equation (1), it is clear that the direction of force exerted on the wire is perpendicular to both the magnetic field and the direction of current.
Hence, the correct option is (d).
