Negative charges can move freely from one object to another. Protons and neutrons never move from object to object. The energy that comes from these charged particles is called electrical energy. When the negative charges move to a neutral object, an electric charge builds up on both objects.

Thus, the electric field direction about a positive source charge is always directed away from the positive source. And the electric field direction about a negative source charge is always directed toward the negative source.

Opposite charges attract each other (negative to positive).

As you already now, opposite charges attract each other. Whether the object with a negative charge moves towards the object with positive charge or visa versa depends on the circumstances. The arrows on the field lines have ALWAYS the convention that they point from the positive charge to the negative charge.

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.

Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge.
