Question
The figure below are two long, parallel wires carrying current in the same direction such that I1 < I2.
- In which direction will wire I1 move?
- If the direction of the current I2 is reversed, in which direction will the wire I1 move now?
Solution
- It will move towards I1. (Two linear parallel conductors carrying currents in the same direction attract each other.)
- It will move away from I1. (Two linear parallel conductors carrying currents in the opposite direction repel each other.)
