The magnetic force between two wires is inversely proportional to the _.
Correct answer: A. Distance
- A. Distance
- B. Current on them
- C. Charge on them
- D. None of these options are correct
Explanation
Magnetic force between two wires is inversely proportional to distance because it is given by:μ0 I1I2 / 2πrHence, Option A is correct.

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.
