Using a magnetic compass to calculate the current in a wire. Learn how magnetic fields, compass deflection, and basic electromagnetism principles connect in a practical physics experiment.

TMS is a noninvasive treatment that uses magnetic fields to help with depression. Up to 70% of people with treatment-resistant depression improve with rTMS. TMS is FDA-approved for depression, OCD, ...

Abstract: This paper proposes an analytical method to calculate magnetic field of nonlinear spoke-type permanent-magnet motors (STPMM) considering static, dynamic, mixed rotor eccentricities and pole ...
