Magnetic Force on a Permeable Wire

1 Problem What is the force per unit length on a wire of radius a and (relative) permeability μ′ when it carries uniform current density J = I ẑ/πa and is placed along the z axis in a magnetic field whose form is Bi = B0 x̂+B1[(x/a) x̂− (y/a) ŷ] before the wire is placed in that field? The medium surrounding the wire is a nonconducting liquid with relative permeability μ = 1. The form of the init...

Magnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...
