Abstract

The invention relates to a method for causing a first body (10; 20) having magnetostrictive properties, and a second body (11), against which said first body is in bearing contact with a certain grip between the contact surfaces, to move with respect to each other while substantially maintaining said grip, wherein a magnetic field profile having a field strength variating in the longitudinal direction of the body is generated in a longitudinal section in said first body and is caused to be moved along the same line as said first body is moved along with respect to said second body. According to the invention electric current is supplied separately to individual coils in a set of coils (12). Furthermore, the supply of current is controlled to cause said coils (12) to generate partial magnetic fields, forming together said magnetic field profile. The invention is related also to a device for carrying out the method. Said device comprises a plurality of sets of coils (12, 12A-12D, 12F-12I), which are arranged along said second body (11), and power supply means are provided for a controllable supply of electric current to said coils (12, 12A-12D, 12F-12I). Furthermore, control means (23-27) are provided for controlling current separately to each of said coils (12, 12A-12D, 12F-12I).
