<p>12 "Electric coil." The coil comprises a coil former with a rodshaped central core portion (1) and two end portions (3, 5) wherebetween a winding (13) made of a conductor (15) is provided. No part of the coil projects beyond a first boundary plane which contains an outer surface (25) of the first end portion (3) and preferably also a contact surface (21, 23) and which encloses an angle of between 5.degree. and 85.degree. with respect to the axis (11) of the rodshaped central portion. The mutual coupling of two or such coils can be very readily varied by mounting the coils in the same position or rotated through 90.degree. or 180.degree. with respect to respect to each other on a substrate (27).</p> |
