Magnets

• Magnets are used worldwide in

  almost all modern devices. It is

  is a material that produces an

  invisible magnetic field.
• An electromagnet is an

  example of a device that

  manifests the interrelation

  between magnetism and

  electricity.
• Like poles repel while unlike poles attract.
• Magnetic flux - as the number of

  magnetic field lines passing

  through a given closed

  surface. It provides the

  measurement of the total

  magnetic field that passes

  through a given surface

  area.
• needs a magnetic field torque to act on

  a current-carrying conductor;

  thus, converting electrical energy

  to mechanical energy.

  Electric Motor
• The application of the

  principles and problem-solving

  techniques of engineering from

  design to manufacturing. Engineers

  analyze their work using the

  principles of motion, energy, and

  force-ensuring that design function

  safely, efficiently, and reliably, all at

  a competitive cost.

  Mechanical Engineering
• Any machine that converts

  mechanical energy to electricity

  for transmission and distribution

  over power lines to domestic,

  commercial, and industrial

  customers. These also

  produce the electrical power

  required for automobiles,

  aircraft, ships, and trains.
