Electromagnetic Swing

Electromagnetism

★Exhibit Content: Magnetic effect of current ★Interaction: Electromechanical interaction ★Operation: Sit on the swing and hold the armrests with both hands. First, push off with your feet to start the swing, then the electromagnetic swing will keep swinging continuously. ★Exhibit Description: This exhibit is an interactive experience device of an electromagnetic swing, allowing two people to participate simultaneously. It mainly consists of a swing device, ground coils, permanent magnets, and a start control device, demonstrating the principle of the magnetic effect of current. After the audience sits on the swing seat under the guidance of the administrator and starts the device, they can personally experience the reciprocating motion of the swing under the action of electromagnetic force, intuitively feel the wonderful physical phenomenon brought by the magnetic effect of current, and deepen their understanding of the basic principles of electromagnetism through interactive experience. ★Scientific Principle: The exhibit utilizes the magnetic effect of current. A magnetic field exists around a current-carrying wire. When the wire is wound into a solenoid, it generates a magnetic field distributed in a ring along the center of the tube, thus creating an electromagnet. The electromagnetic swing is made based on the magnetic effect of current. Its power device consists of a steel plate under the seat and an electromagnet on the platform. When the electromagnet is energized at the right time, it attracts the steel plate under the seat, creating a pulling force on the swing and driving it to swing back and forth.
