Solution

## The correct option is C vertically downwardsAccording to the right hand thumb rule, if right hand's thumb is pointed along the direction of current and fingers are curled around the wire, then the fingers point in a direction along the magnetic field.It can hence be concluded that the magnetic field direction is outside the paper.According to the fleming's right hand rule, pointing the right hand's rule, if we point right hand's middle finger, index finger and thumb perpendicularly and point the right hand's thumb along velocity of conductor and index finger along magnetic field, then direction of induced current is found using the middle finger. By this logic, it can be concluded that induced current is vertically downwards.
