FIELD: electrical engineering. ^ SUBSTANCE: proposed instrument comprises vertically oriented permanent magnet, galvanometre, connected to centrifugal machine housing and sliding contact. Permanent magnet represents cylindrical combined magnet consisting of two identical ferrite ring-like magnets and bearing iron disk arranged there between, the disk edge extending beyond side surface. Aforesaid bearing disk is fitted on shaft made from non-magnetic material and having its shank to be fitted into centrifugal machine chuck. Sliding contact contacts aforesaid extending side edge of bearing iron dick. ^ EFFECT: higher generated emf and improved stability of electric and magnetic parametres. ^ 1 dwg |
