Abstract
This paper describes a haptic device that represents a viscous force and that consists of nonmagnetic metal and a permanent magnet. Using an aluminum plate and neodymium magnets for the device, a user gets resistance at the time when he moves the aluminum plate over neodymium magnets. Then, the device generates force in proportion to an aluminum plate velocity because the force is based on an eddy current. In order to verify the properties of this force, we measure it by mean of motorized linear stages and a load cell. The paper shows the produced power is proportional to relative velocity between an aluminum plate and a neodymium magnet. The paper also describes the device can give us the force which have a periodic vibration.
