In class today, I drew two examples of planar vector fields (i.e., vector fields in the plane). I also described some vector fields in space. Below are pictures of some vector fields in space that are important in physics.
The electric field due to a positive point charge. |
The magnetic field due to a current in an infinitely long straight wire. |
