Like Charges Attract Or Repel

The electric field and the constabulary of allure

In physics, fields draw the distribution of forces in space. Their description thus requires the knowledge of magnitude and direction. Both are expressed through field contours; field forces act in the direction of the contours, and the altitude between the contours indicates their magnitude. (The closer the contours are together, the larger the force.)

In an electric field the management of the field is given by the electric charge of the charged sources. If the charge is negative, the field is directed toward the charge. All electric fields begin on a positive accuse and end on a negative charge.

If two positive charges interact, their forces are directed against each other. This creates a repellent force every bit shown in the illustration. (The same occurs with two negative charges, because their respective forces as well act in contrary directions.)

The electrical field and resulting forces produced by ii electrical charges of the same polarity. The two charges repel each other.

If a positive charge and a negative charge interact, their forces human action in the same direction, from the positive to the negative charge. Every bit a effect opposite charges concenter each other:
