Abstract: A user device comprises a first part and a second part, which is a hand-held body. A movable attachment allows a user to hold the second part by hand and move the first part. A haptic transducer produces haptic effects and comprises a first half and a second half. Of an arrangement of permanent magnets, a first permanent magnet is in said first half and at a second permanent magnet in said second half A coil in said haptic transducer creates, under influence of an electric current, dynamic magnetic forces in the haptic transducer. The first half is attached to said first part of the user device and the second half is attached to said second part of the user device.
