- Calculating magnetic field strength at points around the Earth.

I want to render the Earth’s Magnetic field in a software and simulate solar wind electron interaction with it. How do I calculate the magnetic strength and vector orientation at each point around the Earth up to thousands of km?

Is there a formula?

Or do I need to download a vector field from NASA?
