How to calculate the magnetic dipole moment of a bar magnet?

A bar magnet is not a pure magnetic dipole, but we can calculate the dipole moment by comparing the magnetic fields of a bar magnet and a magnetic dipole at large distances where contributions from ...

Time for ferromagnet to align with magnetic field

For large polycrystaline ferromagnets, the magnetization response to a high strength external magnetic field is usually limited by eddy currents. For magnets that are very small or have very low ...

Time for ferromagnet to align with magnetic field

Well, a bunch of factors come into play. First, you've got the material itself. Different ferromagnetic materials have different properties that affect how quickly their magnetic moments can rearrange ...

Coexistence of a static electric and magnetic dipole

If you want to look at interaction energy, it is a good idea to start with a Hamiltonian for the system, i.e. something that would be conserved in time: With some work you can show that if ...

Why don't the spin states of 47th proton in silver atom matters?

The magnetic moment of a proton is only a thousandth or so of that of an electron. Consequently it will have very little effect on the atom's trajectory through the inhomogeneous magnetic field.
