Physics for IGCSE & O level - Magnets And Currents (Section 5 - No. 11)
What is the impact of eddy currents?
They can produce heat.
They can create a magnetic field.
They always increase the e.m.f.
They tend to oppose the change causing them.
Erläuterung
Eddy currents can generate heat, create magnetic fields, and always act in a direction that opposes the change creating them (Lenz's Law).
