Charge is a fundamental property of matter that causes it to experience a force when placed in an electric or magnetic field. It is measured in units of coulombs (C).
Charge is created when atoms gain or lose electrons. This can happen through processes such as friction, contact with other charged objects, or chemical reactions.
Positive charge is associated with an excess of protons in an atom, while negative charge is associated with an excess of electrons. These charges attract each other, while like charges repel.
The law of conservation of charge states that charge can neither be created nor destroyed, only transferred from one object to another. This means that the total amount of charge in a closed system remains constant.
Charge is the source of both electric and magnetic fields. Electric fields are created by stationary charges, while magnetic fields are created by moving charges. These fields can then exert forces on other charges, causing them to move.
