Concept Overview:

Demonstration of the strength of an electromagnet

Lecturer Procedure

Step(s) to Follow

1. Plug electromagnet into battery.
2. Connect electromagnet to metal plate.
3. Ask for volunteers to separate them.

Expected Result

The magnet and the plate will be very difficult to separate

For improved results, use 4-D cell batteries connected in series rather than a single 9-V battery
