# What is the force acting on an electric current flowing in an electric field, in a direction parallel to that of the field lines?

##### 1 Answer

A current flowing parallel to a magnetic field will have no force exerted on it. The formula is

#### Explanation:

A force acts on electric charges when they move in a direction perpendicular to the direction of a magnetic field. If they are stationary in the field they experience no force, and if they move in the same direction as the field they experience no force.

For individual charges, the formula is:

Current is simply a flow of charge, and the formula looks quite similar:

In both cases, if the angle is
