Hi Craig,
Here is a "clarification" of what a magnetic field is (from wikipedia: Magnetism) ...
"The phenomenon of magnetism is "mediated" by the magnetic field. An electric current or magnetic dipole creates a magnetic field, and that field, in turn, imparts magnetic forces on other particles that are in the fields."
Now does anyone really know what a magnetic field is? We have a cause and we have a field model to explain the effects.
Curiously, I can re-word the statement as follows ...
"The phenomenon of gravity is "mediated" by the gravitational field. A body of mass creates a gravitational field, and that field, in turn, imparts gravitational forces on other bodies that are in the fields."
Like magnetism, we have a cause and we have a field model to explain the effects.
