So, lets go back to the expression for the magnetic field due to a dipole. Plotting B vs. 1/r 3 should be a linear graph with the stuff in the left parenthesis being the slope.

This looks very similar to the electric field due to a dipole (except for the clumps of filings because I can't spread them out). It looks similar because it is mathematically the same.

Direct observations indicate that the magnitude of the Earth’s magnetic axial dipole has decreased over the past 175 years; it is now 9% weaker than it was in 1840. Here we show how the rate of ...

Every so often, Earth's magnetic field flips on its head, turning the magnetic North Pole into the South Pole and vice versa. It last happened 780,000 years ago, and is predicted to occur again in ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

The Standard Model – the current best framework for the forces and particles that make up the universe – only allows for a very small amount of time-symmetry violation, so it predicts that the ...

After six years of collecting data, the muon g-2 experiment released its results and could chart a new path for particle physics.

In essence, they suggested that by positioning a magnetic dipole shield at the Mars L1 Lagrange Point, ... However, we do not guarantee individual replies due to the high volume of messages.

Earth’s magnetic field is a dipole field with two poles, like a bar magnet. When the poles flip, it could cause chaos for future humans.
