Year 12 Physics

Module 6 | Electromagnetism

Content 4: Applications of the motor effect

Lesson 1 | Operation of a DC motor

• investigate the operation of a simple DC motor to analyse:
  – the functions of its components
  – production of a torque ($\vec{\tau } = n\vec{B}IA\cos \theta$)
  – effects of back emf (ACSPH108)

Lesson 2 | DC and AC generators and AC induction motors

• analyse the operation of simple DC and AC generators and AC induction motors (ACSPH110)

Lesson 3 | Lenz's law, DC motors and magnetic braking

• relate Lenz’s law to the law of conservation of energy and apply the law of conservation of energy to:
  – DC motors and
  – magnetic braking
