1.What is the principle of suspension?
Fix the supporting magnets at both ends, and fix them in a suitable position.
Analyzing the generated magnetic field, we can know that the supported magnet is actually in the vertical direction, and it is in the same category.
In a bowl-like magnetic field, the supported magnet will slide to the center of the bowl, that is, the two ends supporting the magnet
In the middle, it is supported by an upward force.
However, it is impossible to float stably just by being lifted, and even the slightest disturbance will cause loss.
To balance, so we will be supported by the magnets from both ends to the middle of the magnets, and move slightly out
At one point, according to the force analysis, the magnet will receive another force, which points to the direction of movement.
Direction, so the tip will lean on the support, so external disturbances can rely on the support
The clever friction in the place is offset. If the adjustment is just right, the friction will be very small.
Very small.
Different solar structures are different, but the principles are the same.
