In this week, we have tested the relationship between two electromagnetic bars in order to see whether or not there will exist repulsion and attraction forces while the current was applied. After we applied the current in one electromagnetic bar, it attracted the other electromagnetic bar. However, there was no repulsion force by applying current. We positioned two electromagnetic bars …

In this week, we have tested the force between electromagnetic bar, magnetic ring, and simple steel materials. We have discovered that the electromagnetic bar can attract magnetic ring without passing through the current but cannot repel it no matter whether there is current. We have learned that the electromagnetic bar can directly attract the magnetic ring because the ring had …
