You have a wire that is carring an AC current through a magnetic field caused by two magnets. The current flowing in the wire is in the X direction and the magnetic field is in the Y direction. In ...

A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...

One of the common modes of scanning probe microscopy (SPM) is Magnetic force microscopy (MFM). As indicated by the name, SPM is used to map magnetic properties. On the nanoscale, MFM probes local ...

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...
