Solution
The correct option is D All of the above
The force that a magnetic field exerts on a current is always perpendicular to the field and to the current.According to Fleming's left hand rule, if the thumb, fore-finger and middle finger of the left hand are stretched to be perpendicular to each other as shown in the illustration, and if the fore finger represents the direction of magnetic field, the middle finger represents the direction of current, then the thumb represents the direction of force. All are perpendicular to each other.
