WebNov 4, 2024 · 2. Eddy currents do not stay in the same direction, nor do they always oppose the direction of the magnetic field in the primary. A good way to understand them is as follows: The eddy currents will create a magnetic field which opposes the change in the magnetic field of the primary. Sometimes this will be in the opposite direction as the ... WebApr 7, 2024 · Eddy Current Definition.
