Magnetic Field Lines in a magnet.

Just making sure that I've got this correct.

Inside a magnet the magnetic field lines goes from South Pole to north pole and on the outside of a magnet it is going from north to south? that way it finishes the loop? Is this correct?

Also does anyone have the TPR physics book? The illustration of the 3D solenoid that they have I think is incorrect because they have a counterclockwise solenoid, but the magnetic field lines are going into the solenoid, when it should be out?

using the right hand rule, the orientation of the magnetic field should be out (this is true), but u need to make sure from where it goes out and where it goes in.

and yeah, ur right about the field lines in the magnet

Remember to reverse the direction of the right hand rule if you're talking about negative charges. If the picture shows current going in the counterclockwise direction, then you're right, it should be pointing out. If on the other hand, the electrons are moving counterclockwise, the electric field should be going into the plane.
