Time-varying fields, electromagnetic induction, and Faraday's law

When fields change in time, electricity and magnetism stop being separate subjects. This topic restates Faraday's law as a statement about fields, with a sign convention that works for any loop in any field, and uses it to find the voltage induced in a stationary loop.

In this topic

  • From statics to dynamics
  • Induction makes a voltage
  • Faraday's law in field form
  • The minus sign and the right-hand rule
  • Transformer emf and motional emf
  • A motionless loop in a uniform field
  • Worked example: a ramping, tilted field
  • Worked example: a sinusoidal field
  • Common mistakes to avoid
  • Key takeaways
