Magnetic force between two wires is proportional to _.
Correct answer: B. Current on them
- A. Distance
- B. Current on them
- C. Charge on them
- D. None of these
Explanation
According to Ampere's law, the magnetic force between two parallel current-carrying wires is directly proportional to the current flowing through the wires. The magnetic field generated by a current-carrying wire interacts with the magnetic field of the other wire, resulting in a force between them. The greater the current flowing through the wires, the stronger the magnetic force between them.The other options, distance (A) and charge (C), are not directly related to the magnetic force between two wires. Distance affects the strength of the magnetic field but does not determine the force between the wires. Charge is not relevant in this context, as the force between wires is primarily influenced by the current they carry.Therefore, the magnetic force between two wires is proportional to the current flowing through them.

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.
