It examines the behavior of internal magnetic fields and their forces, including fringing fields and energy density. Additionally, it discusses magnetic fields' application in MEMS switches, detailing how magnetic pressures and the Lorentz force law facilitate current-induced movements in a beam, enabling logical functions in these devices.
