Two wires carry currents in same direction which is correct
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
When the direction of the current in two parallel wires are same then force of attraction will produce due to a weak magnetic field between wires.Two current carrying conductors attract each other when the current is in the same direction and repel each other when the current is in opposite direction. This can be verified using Fleming's left-hand rule.

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.
