Question
A conducting wire is moving towards right in a magnetic field B. The direction of induced current in the wire is shown in the figure. The direction of magnetic field will be
- In the plane of paper pointing towards right
- In the plane of paper pointing towards left
- Perpendicular to the plane of paper and down‑wards
- Perpendicular to the plane of paper and upwards
The correct answer is: Perpendicular to the plane of paper and down‑wards
According to Fleming right hand rule, the direction of B will be perpendicular to the plane of paper and act downward.
