Magnet through a coil
Move a magnet past a coil and watch the induced current reverse.
What to notice
The lamp responds to changing magnetic flux; a stationary magnet would not induce current.
Key relation
ε = −N dΦ/dt
Try this
Move the magnet faster or add more turns to the coil.
What you can change
- Magnet speed: 0.3 to 2.5 ×
- Coil turns: 3 to 8
- Magnet strength: 0.5 to 3 ×
