# What is an “inclined magnetic field”?

What is meant by an "inclined magnetic field"? How is it different from the usual magnetic field?

-

An inclined magnetic field is just a magnetic field with a nonzero inclination. Inclination is the angle between the direction of the vector $\vec B$ and another, preferred direction in the problem. In astrophysics, they usually mean the radial direction. By the radial direction, I mean the normal (perpendicular) direction to the surface (of the Sun etc.).
