| AC Current Demo | ||
| Description: | Demonstrate the changing direction of AC current. |
|
| Notes: | There are lots of variations to this experiment. You can connect a coil to the galvanometer and move it around between the poles of the large horseshoe magnet. Or put the magnet on a rotation platform, and spin while the coil is suspended above the poles, and note the change in direction of current on the galvanometer. | |
| Location: | LDL-E6. Large galvanometer |
|
| Image: |  The apparatus at rest. Note that galvanometer needle is vertical, and north pole of horseshoe magnet is on the right side |
|
 Magnet on turntable is rotating. Note galvanometer needle is pointing right, and north pole is on right side |
 Magnet on turntable is rotating. Note galvanometer needle is pointing left, and north pole is on left side |
