## Schematic

- A rotating magnet causes a rotating magnetic field also.
- Placing a coil in that field will induce a periodic voltage across it.

## Instructions

- Use the DC motor to rotate the magnet. The coils are provided with ExpEYES.

- Make the connections as shown:

- The frequency of the induced AC will be the number of rotations per second of the magnet.

- When you use two coils, the phase difference between the two signals is decided by the angle between the axes of the coils.

- Adjust the time base to view 4 or 5 cycles
