Electromagnetic force analysis of a driving coil
2012 16th International Symposium on Electromagnetic Launch Technology, 2012Electromagnetic force (EMF) analysis and configuration design of a driving coil is quite important for a coil launcher. Lots of efforts have been focused on armature and control system to improve efficiency or interior ballistic characteristic. By contrast, EMF performance of a driving coil is rarely researched.

Optimal Coil Currents in Electromagnetic Flow Tomography
IEEE Sensors Journal, 2017Electromagnetic flow meters are a gold standard in measuring the mean flow velocity of conductive liquids and slurries in process industry. A drawback of this approach is that the velocity field cannot be determined. Velocity field information is important for characterizing multiphase flows in the process industry.

Multi-Axis Electromagnetic Moving-Coil Micro-Actuator
Design Engineering and Computers and Information in Engineering, Parts A and B, 2006This paper presents the design and proposed fabrication of an electromagnetic (EM) micro-actuator capable of independent force output in two orthogonal axes of motion. This actuator enables independently controlled in- and out-of-plane motion when coupled with a suitable flexure. An electromagnetic force model is presented.
