Learning Outcomes

  • Explain the operation of motors, generators and transformers using knowledge of magnetic circuit laws and fundamental circuit laws.
  • Solve problems related to the operation, characteristics and implementation of motors, generators and transformers.
  • Determine electric and magnetic field strengths and their effects in and around electrical machinery.
  • Predict and model the effects of magnetic induction on moving parts of machinery by making use of Maxwell's equations.
  • Analyse, draw conclusions and report the results of physics and electrical machines experiments.
