Even when the net charge is zero, it can be distributed non-uniformly (e.g., due to an external electric field or to molecular motion), ... In contrast, electric current is the flow of electric charge through an object, which produces no net loss or gain of electric charge. Although charge flows between two objects during...

The magnetic properties of the wire are largely independent of the field due to charge flow. Current moving along a wire causes an orthogonal field due to the idea of charge motion. A charge in motion produces a field with electric and magnetic components.

Acceleration toward the center of circular motion. ... This ordinary water produces steam, which will turn ... Electric lines of force represent the direction that a positive test charge would move in an electric field. By convention, they originate at positively charged objects and terminate at negatively charged objects.
