The present invention relates to an electronic hula-hoop for generating a centrifugal force by an electromagnet. More specifically, multiple rail magnets having an identical pole are disposed along the inner surface of a body of a hula-hoop, and a rail is formed on the outer side in the body. A rotation vehicle having a roller installed thereon is seated on the rail to glide along the rail, and a rotation magnet having the identical pole as the rail magnets is installed in one side of the rotation vehicle, so an angle is adjusted. Accordingly, a gliding speed of the rotation vehicle is changed by repulsion of the identical pole, and a rotation speed of the hula-hoop is increased or decreased. A transceiving device is further installed on the rotation vehicle to wirelessly communicate with a remote controller or a smart phone, so a rotation speed is adjusted and various pieces of information are provided. The electronic hula-hoop can provide various services by being connected with an application. |
