What's the difference between magnetic field and electric field lines?
Does $d\vec B$ point in the direction you would experience a force if you were a moving charged particle at that point? I know for a fact the electric field and electrostatic force are parallel, but since $F = q\ \vec v \times \vec B$ for magnetic forces. Does that actually mean though that if, say, in the following graphic:
Where the dot is a wire going in and out of the page, that the $d\vec B$ vectors are not showing how a moving charged particle will move in the field?
Basically, I feel justified in thinking electric field lines communicate how a test charge will move at any given point in space.
How can I juxtapose this with magnetic field lines>
