Essential Physics Demo: Variable Coil Electromagnet

Affordable, easy, fun.

  • Excite your students about learning core physics concepts
Present these demonstrations in front of your class to excite your students about learning core physics concepts. Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics.

The variable coil electromagnet has 6 different coil options:100, 200, 300, 400, 500 and 600 coils. A steel hook underneath gives students the opportunity to measure the strength of the magnetic field generated by varying different number of coils. It also allows study into Ohm's Law, if a constant voltage is applied to each coil the measure current will drop as the number of coils increase. Includes a variable coil electromagnet and a 5 Newton spring scale. Required but not included is a 12 V power supply.
