Practical Ideas:
|
- Moving magnets in a wire coil to create an emf, emphasizing direction of movement, direction of the magnetic field and the direction of the current induced
- Dropping a magnet through a copper tube to demonstrate Lenz's Law - Using changing current through 1 Helmholtz coil to create an emf in the Helmholtz coil |

Pracitical Ideas:
|
- Using a capacitor with a full wave rectifier to create a smooth DC output (as seen on an oscilloscope)
- Using a simulation (Falstad) to create an RC circuit and noting the effects of changing R and C on the time constant |
