If the direction of current in two parallel wires is in opposite direction, then the wires will:

Correct answer: B. Repel

  • A. Attract
  • B. Repel
  • C. Both a and b
  • D. None of these

Explanation

When the current flows in the opposite direction in two parallel wires, the magnetic fields produced by the wires interact in such a way that they repel each other. This is because the magnetic field lines around each wire are in opposite directions, resulting in a repulsive force between the wires.

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.
