magnetic force on moving chargesFigure 5: Magnetic force on moving charges. The magnetic forceFis proportional to the charge and to the magnitude of velocityvtimes the magnetic fieldB. The magnetic force on a moving charge reveals the sign of thecharge carriers in aconductor. Acurrentflowing ...
When an electric current traverses a straight wire, it induces a magnetic field whose lines of force are concentric circles centered around the wire. This configuration illustrates the intimate relationship between electricity and magnetism, highlighting how electrical currents can create magnetic environmen...
This paper discusses the force/current relation for a solid magnetic thrust bearing. The particular bearing was designed for a laboratory pump as a bearing/load cell to support the shaft as well as measure the thrust forces on the impeller. The current/force relation is also important for magne...
Magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected, but not the speed. This is typical of uniform circular motion. The...
Oersted discovered that a compass needle deflects near a current-carrying conductor, showing it exerts a force on the needle. In 1821, Faraday found that a current-carrying conductor also deflects in a magnetic field, indicating mutual forces between the
1b. The robot approaches the targeted ulcer on a gastric tissue through performing translational motion, and the adhesive film of the side layer then adheres to the gastric tissue by applying magnetic gradient force \({F}_{m}\). By altering the direction of the magnetic field, the magnetic...
