6.11 understand that there is a force on a charged particle when it moves in a magnetic field as long as its motion is not parallel to the field
if any charged particle (eg. a current running through a wire), it will experience a force from the magnetic field.
the introduction of a new magnetic field causes the magnetic field lines to overlap, and the stronger field lines push the particle to an area of weaker field lines (see more information here)
if the wire is running parallel to the field, the force will be felt along the wire, not perpendicular to it, so it does not move
