Magnetic flux density B is a vector quantity and thus represents a force. However most texts state that the magnetic force is perpendicular to the direction of B, which is tangential to the magnetic field line at any give point. I assume that this magnetic force refers to the Lorentz force. So my question is: 1) What exactly does the direction of force B represent? 2) Would it be correct to state that it is the force B that acts on a test magnet causing it to orient along a magnetic force line?
