Part B
The Transformer (Boosting or Lowering Voltage)
Changes voltage using two coils and a magnetic field
Step-up transformer: increases voltage
Step-down transformer: decreases voltage
Works only with AC
Electromagnetic Induction
Producing voltage by changing a magnetic field
Moving a wire through a magnetic field creates electric current
Basis for generators and transformers
Generators & Alternating Current (AC)
Generators convert mechanical energy → electrical energy
Spinning coils in a magnetic field produce AC
AC current constantly reverses direction
Power Production
Large generators in power plants make electricity
Energy sources: coal, natural gas, nuclear, wind, hydro, solar
Turbines spin generators to create AC
Field Induction
Changing magnetic fields create electric fields
Changing electric fields create magnetic fields
