How do you keep the metal object from sticking to the magnet when building a magnetic damping device? 
Magnetic damping is a phenomenon where a magnetic field is used to reduce the motion of a moving object. It is commonly used in instruments such as galvanometers and seismometers to reduce the oscillations caused by the movement of the object.
Magnetic damping works by creating a magnetic field that interacts with the moving object and creates a resistive force. This force acts in the opposite direction of the motion and helps to slow down the movement of the object.
The benefits of using magnetic damping include increased accuracy and stability of the instrument. It also reduces the time it takes for the instrument to come to rest, allowing for faster measurements and readings.
Some real-life examples of magnetic damping include the use of magnetic brakes in roller coasters to slow down the cars, and the use of magnetic damping in watches to reduce the impact of external forces on the movement of the hands.
One limitation of magnetic damping is that it only works on objects that contain magnetic materials. It also has a maximum damping force that it can exert, so it may not be effective in cases where a very strong damping force is needed.
