> Normally, these little electron orbits all point in more or less random directions. But in the presence of a strong enough external magnetic field, the electron orbit will tend to get aligned so that its “north pole” points in the same direction as the magnetic field. By my estimate, this would happen at a few hundred Tesla. Isn't this exactly what happens in an MRI machine?
