Abstract

In this study a technical solution is proposed to achieve an intense 50 Hz alternating magnetic field and a static magnetic field made by permanent magnet at the same place. A compact coil built by Bitter coil concept is customized to support alternating current, thus creating an alternating magnetic field. A complementary permanent magnet assembly is built around it to achieve the superposition of both fields along the axis of symmetry. Results from the experimental model are compared to both numerical and analytical models.
