Eddy currents
What Eddy currents means in Physics A-Level, as defined for AQA.
Definition of Eddy currents
Check what you remember
Read the wording for your board, then hide it and explain Eddy currents in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Currents induced in the iron core by changing magnetic flux, which circulate and heat the core.
