Magnet polepiece design for uniform magnetic force on superparamagnetic beads
Here we report construction of a simple electromagnet with novel polepieces which apply a spatially uniform force to superparamagnetic beads in an optical microscope. The wedge-shaped gap was designed to keep ∂B(x)∕∂y constant and B large enough to saturate the bead. We achieved fields of 300–600 mT...
