Unit 21 Electromagnetism
... When the current in each conductor flows in the opposite direction, the strips repel. However, when both currents are in the same direction, they attract each other. We can summarise the forces between two parallel current-carrying wires as: Definition: Current is opposing directions cause repulsio ...
