MAKING AN ELECTRIC CURRENTS WITH MAGNETS

• A device that uses a magnetic field to transform mechanical energy to electric energy.

  Electric generator
• An electric current that flows in one direction.

  Direct Current
• An electric current that changes direction in a regular pattern

  Alternating current
• A shaft with a set of blades that spins when a stream of pressurized fluids strikes the blades. This transfers the mechanical energy of a steam of wanter, steam, or air, to the generator.

  Turbine
• A device that changes the voltage of an alternating current.

  Transformer
• 2 types of transformer:

  • Step-Down Transformer
  • Step-Up Transformer
• This transformer uses fewer loops in the secondary coil than in the primary coil, the transformer's output voltage is less than the input voltage.

  Step-down transformer
• The number of loops in the secondary coil is greater than the number of loops in the primary coil, the output voltage is greater than the input voltage in this type of transformer.

  Step-up transformer
• An example of step-down transformer

  
• An example of a step-up transformer

  
• He discovered the principle of generators
