Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...

An effective transformer design requires a determination of the peak values of the magnetic flux, the magnetic field strength, and the permeability of a core at low and high frequencies. These ...

Placing each of these four H-coils at different distances to the surface of the specimen "enables us to evaluate the influence of the position of the H-coil on the measurement accuracy of magnetic ...
