If two parallel conductors carry currents flowing in the same direction, the conducts will
A
attract each other
B
repel each other
C
both move in the same direction
D
have no effect on each other
Verified Correct Answer: A.
Physical Principles & Numerical Solution
When currents flow in the same direction in two parallel conductors, they generate magnetic fields that interact to produce an attractive force between them. Conversely, if the currents flow in opposite directions, the conductors will repel each other.
