Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.

when current is reversed in the direction the force due to magnetic field is also reversed

As we know that the formula of force will be given as

so here if the direction of current is reversed the the force vector also reverse its direction

So we will have the direction of force is also reverse and it will move downwards now

we need to know the time interval during which the force acts. impulse of force = momentum change

mass and volume are the answers you are looking for
