The braking magnet arrangement used, particularly, for an electricity meter exhibits two permanent magnets (1, 2) arranged in a holder (4). A rotor disc (3), on which a braking torque generated by the braking magnet arrangement is exerted, moves through the air gap provided between the two permanent magnets (1, 2). The two permanent magnets (1, 2) are arranged in such a manner that their direction of magnetisation extends parallel to the surface of the rotor disc (3) located in the gap. Such an arrangement allows the dimensions of the braking magnet arrangement and the material required for the permanent magnets (1, 2) to be reduced. <IMAGE>
