the magnetic flux linked with the coil changes, which induces an emf in the coil. Among the above two statements: c) ...

Abstract: Helmholtz coils are widely used to generate homogeneous magnetic ... to investigate the interconnections between these parameters and their effects on magnetic flux density and field ...

Deep magnetic focusing (DMF) by multiple coaxial coils, a sort of 3-D SMF, is firstly proposed in this paper, where magnetic field becomes maximum at the focal range in longitudinal direction. DMF is ...
