Electromagnetic Induction
How to create electric potential without a power source?
Move the coils within the field of the permanent magnet and monitor the voltage generated in the coils on the display. You can examine how it depends on the speed of the movement, the winding and the angle of the coils. In this experiment you will discover that electric voltage and current can be generated from virtually nothing even in a circuit without a traditional power source (battery) by merely moving wires and coils in a magnetic field.
