1. The law of charge states that
Opposite charges are strongest and like charges are weakest.
The force between charges gets stronger the father they are away from each other.
Charge makes electricity a very weak force compared to gravity.
Opposite charges attract and like charges repel.
The area around a charged object that exhibits a force when another charge is present is called
a magnetic field.

induction.
voltage.
If charge separates temporarily when in the presence of a charged object, we call the charging
a miracle!.
