DIY magnetic weather vane

A fan suspended in a magnetic field does not spin by itself, but it can be driven into rotation by an air stream. In order not to go beyond the field, the axis of the weather vane has a mounting point. For such a craft, you need six magnets with a hole, the design can be made of ice cream sticks and an ordinary ballpoint pen.

Without even rotating, due to the levitation of its axis, this weather vane can become an interior decoration and an interesting gift.
