Factors on which Magnetic Force Depends:
The magnetic force depends on following factors:
1. Nature of Pole: Like poles repel each other and unlike pole attract each other.
2. Distance among the poles:
3. Magnetic force is directly proportional to the square of the distance among the two poles.
4. Strength of the poles: The greater the strength of the poles the stronger the magnetic field.
