The anemometer of ถ้วยลม DIY Aerovane mainly drives the magnet with eight pole magnetic impact through the wind blade. When the aluminum plate connected with the pointer will produce some eddy current, there will also be magnetic effect. Along with the magnetic field, the magnetism of the magnet and the eddy current on the aluminum disk will also attract and repel each other. Therefore, the faster the wind blade speed is, the higher the pointer will be.
