Theoretical analysis and experimental result indicate that this technology can pick-up the signal change of planar coil and hold high sensitivity and stability using appropriate parameters.

The device consists of a square planar coil, a spring support structure, and permalloy magnet film.

This paper presents the fabrication and theoretical analysis of an electromagnetic microrelay using a planar coil.

In order to solve the problem of long-term stability in the conventional silicon flexural accelerometer,an accelerometer based on plane helix was tentatively designed,which used the new magnetic supporting equipment.

Aiming at the feature of fully open magnetic resonance imaging system,a new approach to the design of uniplanar gradient coils was proposed.

The magnetic flux density distribution of flat spiral coil simulation by impulsive current usually used in electromagnetic metal forming is researched.

Based on the new idea of controlling welding stress with trailing electromagnetic force,the electromagnetic force in flat spiral coil-aluminum sheet system was simulated with finite element software ANSYS.
