PURPOSE: circulatory system learning model passes through construction real heartbeat model use electromagnet to understand by increasing for improving the study of understanding level and temper that student directly observe the heartbeat of display simultaneously with experimental data is obtained about heart. ;CONSTITUTION: if electric current, which one of is flowed into suddenly on (1) two iron core, is wound with coil, by the electromagnet using these principles, two different iron cores generate magnetic field when being forced through induced magnetic field each other wherein and have resisted other side while movement. Heartbeat is expressed by being repeated periodically above-mentioned phenomenon. ;The 2013 of copyright KIPO submissions
