The direction of the magnetic line 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 force depends on the direction of the current and the direction of the magnetic field. Of these two, the direction of the current is in options so that will be 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.
