Summary:An arrangement for a lithography apparatus has a component and a weight compensating device to compensate for a weight of the component. The weight compensating device includes a first magnetic device and a second magnetic device. The first magnetic device is designed to exert a first magnetic force on the component. The first magnetic force exceeds the weight of the component. The first magnetic force acts counter to the weight of the component. The second magnetic device is designed to exert a second magnetic force on the component. The second magnetic force acts in the direction of the weight of the component. The first magnetic force corresponds to the sum of the second magnetic force and the weight. The second magnetic device is designed to reduce the second magnetic force at the same time and by the same absolute value as the first magnetic force.
