Abstract: A magnetic windblown device has a housing, a windblown assembly, a magnetic assembly, a power assembly, a decoration, and at least one magnetic element. The windblown assembly and the magnetic assembly are mounted inside the housing. The power assembly is mounted in the housing and is electrically connected to the windblown assembly and the magnetic assembly. The decoration and the magnetic element are mounted in the housing. The windblown assembly generates airflow to make the decoration swing. The magnetic assembly changes the magnetic field to rotate and move the magnetic element. Office staff feels relaxed and inspired by watching the swinging decoration and the rotating/moving magnetic element.
