Question

  1. briefly explain how an electric motor works. the magnetic field is causing a push or pull and then electric energy carried by current is converted into kinetic energy of the what is the function of an - electric - generator in terms of electric power and motion? 9. briefly explain how an electric generator works.

Explanation:

Brief Explanations

An electric motor works based on the interaction between magnetic fields and electric - current. When an electric current passes through a coil placed in a magnetic field, a force acts on the coil due to the magnetic field, causing it to rotate. This converts electrical energy into mechanical (kinetic) energy. An electric generator is the reverse. It converts mechanical energy (motion) into electrical energy. When a conductor (such as a coil) moves through a magnetic field, an electromotive force (emf) is induced in the conductor, generating an electric current. The function of an electric generator in terms of electric power and motion is to transform the mechanical motion of a prime - mover (like a turbine) into electrical power for distribution and use.

Answer:

  1. An electric motor uses the interaction between magnetic fields and electric - current. Current in a coil in a magnetic field causes rotation, converting electrical energy to kinetic energy.
  2. The function of an electric generator is to convert mechanical motion into electrical power.
  3. An electric generator induces an emf in a conductor moving through a magnetic field, converting mechanical energy into electrical energy.
