電磁石パワーラボ｜電流とコイルの実験

This science teaching material for 5th graders to 2nd year middle school students allows them to experiment with the workings of electromagnets by changing the number of turns in a coil and the current.

By changing the number of turns, the magnitude and direction of the current, and the power source, the magnetic field lines, the poles, and the number of clips attracted will change. Students can record the conditions and compare two experiments, or verify their predictions and results with missions involving the number of turns, current, and poles.

They can observe the invisible changes in magnetic force through diagrams and movements, and learn how to conduct experiments by changing conditions one by one.
