MAGNETIC-STRUCTURE DESIGN METHOD

The method described provides a simple procedure for the design of str uctures intended to generate a magnetic field that follows a specific variation law in an air gap. The emphasis is laid on design rules deri ved from well known theorems such as the superimposition principle, th e easy axis rotation theorem, and the image theorem. An example is giv en for a linear displacement sensor application. Magnetic structures f or producing trapezoidal or triangular profiles of the magnetic induct ion consist of simple yoked and yokeless configurations. An experiment al device has been designed and built with the help of analytical and numerical calculations.
