Electromagnetic Force on a Magnetic Monopole [PDF]
Progress of Theoretical Physics, 1984 The electromagnetic force on a magnetic monopole in matter is shown to be F=g(H-v\ifmmode\times\else\texttimes\fi{}E/c) when there is only one magnetic monopole in matter. The relation between this force and the conservation law of momentum is discussed. The case in which a macroscopic number of magnetic monopoles exist in matter is also discussed.

On the electromagnetic force on a polarizable body [PDF]
American Journal of Physics, 2002 The force on a macroscopic polarizable body in an inhomogenous electromagnetic field is calculated for three simple exactly solvable situations. By comparing different approaches, we pinpoint possible pitfalls and resolve recent confusion about the force density in ferrofluids.

Force spectroscopy with electromagnetic tweezers [PDF]
Journal of Applied Physics, 2021 Force spectroscopy using magnetic tweezers (MTs) is a powerful method to probe the physical characteristics of single polymers. Typically, molecules are functionalized for specific attachment to a glass surface at one end and a micrometer-scale paramagnetic bead at the other end.
