PURPOSE: A circulation system learning model is provided to improve an understanding level of learning through an increase in understanding about a heart exercise and the acquisition of experimental data while students directly observe a display of a heartbeat by constructing a real heartbeat model using electromagnets. CONSTITUTION: If a current suddenly flows in one of two iron cores(1) on which a coil is wound by using a principle of an electromagnet, two different iron cores push each other through an induced magnetic field in which a magnetic field is generated and resists the other side at the same time. A heartbeat is expressed by periodically repeating the above mentioned phenomenon. |
