Given information
We are given that the current moves in closed-loop and the magnetic field is perpendicular to the plane of the circuit. Bar of weight 
and length 
is placed in the field of 
.
We have to find the constant current flow is needed to accelerate the bar from rest to 
in a distance of 
m and in what direction must the magnetic field point?
Step-by-step explanation
Step 1.
Here, the current is constant, then the magnetic force is constant. So we have a constant acceleration, so the equations of motions can be used.
Acceleration, 
Net force,
