Magnets
- THE RING AND THE INNER MAGNET ARE DISGNED SO THE MAGNETS REPEL AND CANCEL THE WEIGHT OF THE OIL BATH SO IT DOES NOT WEIGH DOWN THE SPEAKER
- THE SPHERE MAGNET AND THE RECESSED MAGNETS ATTRACT SO THE OIL BATH CAN PIVOT
There is also a cylinder magnet inside the arrow shaft that repels the ring magnet to contract the weight of the oil bath.
The force of the repelling magnets was calculated. The figure below shows the force of two ring magnets repelling and how it decreases when further away. The same thing was done for the disk magnet, then a average was made between the graphs to see what the force would be with the ring and cylinder magnet.
