Question

Two long, straight, parallel wires are carrying a current I in the same direction. Select all that apply to the force felt by one wire due to the other.

a. It is parallel to the current in the other wire.
b. It is perpendicular to the field produced by the other wire.
c. It is perpendicular to the current in the other wire.
d. It is parallel to the field produced by the other wire.

Answer 1

Answer: Option C.

It is perpendicular to the field produced by the other wire

Step-by-step explanation

It is perpendicular to the field produced by the other wire because the force between the two parallel line is attractive in nature because the current is flowing in the same direction.

The two parallel wires carrying current in the same direction attract each other and their magnetic field will be attracted to each other.
