Question

In physics, what does Gauss’s law relate?

Options

• A tiny compass needle to a moving charge

• The area of a surface to the shape of a bar magnet

• The field passing through a closed surface to the source enclosed by that surface

• The orientation of a surface to the force of a wire element on itself

Answer 1

Gauss’s law relates the field passing through a closed surface to the source enclosed by that surface. The magnetic case has zero net flux through every closed surface.
