An electric field causes an electric force on other charges that enter the field. The electric field is defined as the amount of electric force per charge at a point in space.

A point charge is concentrated at a single point in space. Learn about the formula used to find the magnitude and direction of the electric field between two point charges, and see two examples of how to calculate the magnitude of an electric field.

For example, if you place a positive test charge in an electric field and the charge moves to the right, you know the direction of the electric field in that region points to the right.

That property is called the electric field. Charges shape the space around them, forming an electric field that interacts with other charges. The tutorial covers Coulomb's Law, electric field lines, and the role of distance in field strength. Ideal for premed students delving into electrostatics.
