The magnetic force between two wires which are having current in opposite direction will:
Correct answer: B. Repel each other
- A. Attract each other
- B. Repel each other
- C. Experience no force between them
- D. None of these options are correct
Explanation
The magnetic force per unit length between two parallel wires is given by; F/ l = (μo/ 2π) (I1I2 / d)If the conductor carries the current in the same direction, then the force between them will be attractive.If the conductor carries the current in the opposite direction, then the force between them will be repulsive.Hence, B is the correct answer.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
