Generator effect and potential difference graphs

Magnetism and electromagnetism • Induced potential and transformers

Key concepts

What you'll likely be quizzed about

  • The generator effect occurs when a conductor moves through a magnetic field, or when the magnetic field around a conductor changes.
  • This movement induces an electromotive force (EMF).
  • Faraday's law quantifies this relationship, stating that the induced EMF is directly proportional to the rate of change of the magnetic flux through the conductor.
  • The practical application of this effect is seen in generators, where mechanical energy is converted into electrical energy.

What do curved lines on a potential difference graph signify?

Click to reveal answer

Curved lines indicate a non-linear relationship, suggesting variable resistance in the circuit.

Key notes

Important points to keep in mind

The generator effect is related to magnetic flux change.

Potential difference graphs reveal circuit behavior and resistance details.

Linear graphs follow Ohm's law; curved graphs indicate non-linearity.

Faraday's law is key for understanding induced EMF.
