The direction of the magnetic lines of force depends upon:

Correct answer: D. Direction of the current

  • A. Nature of the material of the conducting wire
  • B. Area of the conducting wire
  • C. Amount of the current
  • D. Direction of the current

Explanation

The direction of the magnetic lines of force can be found using the right-hand rule. If you point your right thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines.

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.
