Magnet Hints and Tips Master

The magnets in the Model Wave Generator are very strong. In order to separate them, students should slide/ twist them apart. Please also take the following precautions: ƒ Wear safety glasses when handling magnets. ƒ Use caution when handling the magnets. Fingers can easily be pinched between the attracting magnets. ƒ When you set the magnets down, place them far enough away from each other that the magnets won’t snap back together. ƒ When you are finished with the magnets and ready to store them, put a small piece of cardboard between them. ƒ Keep magnets away from your computer screen, cell phone, debit/credit cards, ID badges, and medical devices.

If the galvanometer does not display a reading, check the following: 1. Test the model with a multimeter. 2. Was the wire coating removed from the ends of the wire? Has the exposed wire oxidized? 3. Were the coils of wire wrapped tightly and in the correct number?
