Webmagnetic field of a small bar magnet is equivalent to a small current loop, so two magnets stacked end-to-end vertically are equivalent to two current loops stacked: The potential energy on one dipole from the magnetic field from the other is: UB=− ⋅ =−μ12 12B μzz (choosing the z-axis for the magnetic dipole moment) WebThe magnetic dipole moment of a D82 magnet is 0.422 A m 2. Also, this word “moment” sounds like jargon. It’s a fancy word that physicists and engineers use when they really mean “torque.”. It’s a force applied at a distance, like foot-pounds of torque applied with a wrench. The magnetic moment torque of a D82 magnet is 0.422 A m 2. hip knives https://veritasevangelicalseminary.com
