Electromagnetic force:-
- Electromagnetic force is a combination of electrostatic / electric force and magnetic force.
- The force acting between two static electric charges is called electrostatic force.
- The force acting between two magnetic poles is called magnetic force.
- The electric and magnetic forces are inseparable because a moving charge produces a magnetic field, and this field exerts a force on the moving charge.
- Hence , both these forces are treated under a general force called Electromagnetic force.
- Electromagnetic force is much stronger than gravitational force, because inspite of having masses of electrons, they repel each other instead of attraction.
