A current I flows to the right and is perpendicular to a magnetic field B. A magnetic force per unit length F/L acts upward on the conductor. What is the magnitude and direction of the magnetic field in the region through which the current passes.

Expert Solution
Step 1 Concept
A current-carrying conductor placed in an external magnetic field produces a force.
The direction of the force on a current-carrying conductor placed in an external magnetic field is given by Fleming’s Left Hand Rule. It states that " If we hold the thumb, forefinger and middle finger of the left hand in mutually perpendicular to each other such that the forefinger points in the direction of the magnetic field, the middle finger points in the direction of the current, then the thumb points in the direction of force (motion) of the conductor".
