What causes electrical charges to attract and repel?

Answer 1

It is made out of small particles, smaller than atoms called electrons.It is made out of small particles, smaller than atoms called electrons.

Answer 2

An electric current going in one direction will be attracted to another electric current going in the same direction. This is a pretty weak attraction and the currents usually have to be several amps and pretty near each other to see the effect. If the currents are going in opposte directions they will repel each other. Currents can also attract or repel magnets. For example if a wire is wound in a long coil (like a spring) then it will act like a bar magnet and attract or repel another bar magnet, or for that matter, another coil of current. This effect is also weak and to make the effect stronger the coil of wire is usually wound on a piece of iron or even a nail.

Answer 3

Electricity is closely related to electrons. It is the movement of the electrons from an atom to an another in a direct current circuit, and the ''vibration'' of those in an alternate current circuit.

Answer 4

An electric current doesn't necessarily involve multiple charges - a current describes a moving charge. The unit of current is Amperes, which are equivalent to Coulombs/Second. Thus, current is the relationship between the movement of charge and time, or a description of how fast a charge moves. This can refer to a single charge, and the issue of attraction v. repulsion is not relevant.

Answer 5

Electrical charges attract and repel based on their polarity. Like charges (positive-positive or negative-negative) repel each other due to the electromagnetic force between them, trying to reach a lower-energy state. Opposite charges (positive-negative) attract each other, as the electromagnetic force pulls them together to balance their charges.

Answer 6

It dependes on the different types of charges the same charges will relel and different charges will attract.
