- Electromagnetic Induction
- How voltage/current is generated (generator)
- Produces an alternating current
- to make a bigger current, increase: Number of turns, Strength of magnet, Speed of coil movement
- How voltage is made
- Coil moves, wire cuts magnetic field lines, experiences a change in magnetic field, voltage induced
- Electromagnetism vs Electromagnetic Induction
- Electromagnetism
- To create a bigger force increase: number of turns, strength of magnet, current
- How a force is made
- current in wire produces a magnetic field, field interacts with permanent magnetic fields, we get a force from where the field is strong to where it is weak
- A Loudspeaker uses this principle
- Left hand rule = Thumb (Thrust), First finger (field) seCond finger current
