Strength of Electromagnet

Demo

Electromagnet, Iron plate connected to ropes, 9V battery lay on a table

Concept Overview:

1. Demonstration of the strength of an electromagnet

Lecturer Procedure

Step(s) to Follow Expected Result

1. Plug electromagnet into battery.

2. Connect electromagnet to metal plate.

3. Ask for volunteers to separate them.

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
