What is electromagnetic force? Please simply explain.

A definition we all know about electromagnetic energy is that the amount of work done to bring one-coulomb charge from one point of the circuit to the source and back to that point is called the electromagnetic energy of the source. But many people do not understand this definition. So I am presenting electromagnetic energy in a simple way.

If you place a marble on a straight and horizontal path, the marble will stay in its position. One does not go forward or backward. Now if the marble is placed on a sloping road, the marble will continue to roll down the sloping road. Here you are not applying force to the marble. No force was previously applied to the marble. But still, the marble is rolling. Because the floor is designed in such a way that the ball is applied to the marble by itself. Here, the steeper the road, the more force will be applied to roll the marble.

The battery plays the same role as the road in the circuit. A high positive charge is applied to one terminal of the battery and an equal amount of negative charge is applied to the other end. Positive charge means electron void. And negative charge means an excess of electrons. Due to this imbalance, more electrons move from the negative end toward the positive charge. The greater the amount or difference in charge of the battery, the faster the charge will run in the circuit. We call the electromagnetic force on which the battery force is applied to the electrons. That is, the electromagnetic force is the force that pushes the charge to move in the circuit.
