What happens if, instead of moving the bar, I attach the rails to a DC voltage source ? Assume the positive end of the voltage source would be along the top bar and negative end on the bottom.

Question

What happens if, instead of moving the bar, I  attach the rails to a DC voltage source ? Assume the positive end of the voltage source would be along the top bar and negative end on the bottom.

Answer

Current would flow  up  through the bar, causing a force (and therefore acceleration) to the  right.

Answer

Current would flow  up  through the bar, causing a force (and therefore acceleration) to the  left.

Answer

Current would flow  down  through the bar, causing a force (and therefore acceleration) to the  right.
