Calculation of Magnetic Field Lines
I am doing some research on how to calculate magnetic field lines for a bar magnet.
So far I have found the following equations:
\begin{align}
\frac{B_r}{B_\theta} &= \frac{d_r}{rd_\theta}\\
B_r&...

Why is the geomagnetic north pole at a different location from the magnetic north pole?
According to this site
Magnetic North, Geomagnetic and Magnetic Poles
The Geomagnetic poles (dipole poles) are the intersections of the Earth's surface and the axis of a bar magnet hypothetically ...
