DEM30 - Magnetic Effect of Current on Parallel Conductors


- To show the force between two parallel current-carrying conductors.



Connect the leads from the D.C. 30 amp 1 volt terminals directly to the Parallel wire apparatus.
Turn on the power supply and slowly turn up the DC control to maximum to observe maximum deflection... not more than 10 seconds)

Parallel wires carrying currents in opposite directions REPEL each other.
