Abstract: Helmholtz coils are widely used to generate homogeneous magnetic fields. Various parameters influence the magnetic field strength and homogeneity, including coil shape, size, spacing, ...

Solenoid engines are an exciting and fun project to build. In this video, we will create a powerful solenoid engine using LEGO. The basic concept involves an electromagnet that pulls a piston into the ...

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 ...
