We know that, Magnetic force is given as:
F= l(i X B) where, l: Length of the current carrying material and,
i: current B: Magnetic field.
Direction of force can be determined from right hand thumb
rule.
Hense, from Right hand thumb rule, Force on the conductor is in
downward direction.
Hense, upper edge is at higher potential.
