Researchers at ETH Zürich have built the most powerful miniature superconducting magnets ever demonstrated, ...
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 ...
Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
