# Illustration Symbols for the magnetic field direction perpendicular to the plane

Shown is the direction of the magnetic field $$\boldsymbol{B}$$:
• A cross with a circle around it means that the $$\bold symbol{B}$$-field points into the screen (away from you).
• A dot with a circle around it means that the $$\bold symbol{B}$$-field points out of the screen. So it is pointing at you.
