SUMMARY
The magnetic field strength on Earth's surface at either pole is approximately 0.00006 tesla. This value is derived from the Earth's magnetic dipole moment, denoted as D_0. The relevant equation for calculating magnetic field strength is B = μ₀(NIA), where μ₀ represents the permeability of free space, N is the number of turns, I is the current, and A is the cross-sectional area. For precise calculations, refer to the dipole field data available on resources such as Wikipedia.
