K1-05: FORCE BETWEEN CURRENT-CARRYING COILS

ID Code: K1-05
Purpose: Demonstrate that current-carrying coils produce magnetic fields and interact like bar magnets
Description: Two coils are aligned with their currents moving around in the same direction, so their magnet fields will be North-to-South. They will attract each other when the current is started by pushing the switch (click here for video). Reversing the wires on the top can put any combination of magnetic poles adjacent, getting either attraction or repulsion (click here for video). A small bar magnet, included with the demonstration, can be used to see the forces between one of the coils and the magnet, again using any combination of magnetic poles (click here for video).
