To eliminate eddy currents you can cut small slits in metals. This will prevent larger eddy currents from occurring. Placing insulators between small laminations can also help to protect against eddy currents.

Why is energy lost in transformers?
Some energy is lost in most machines, in most energy transformations. In the case of transformers, the main problem is eddy currents - unwanted currents, that are minimized, but not eliminated completely, by laminating the iron.
Eddy current in transformer?
Yes, a transformer has eddy currents.
How does currents create a garbage patch in the ocean?
eddy currents
Why transformer core cuts thin sheet?
Transformer cores are made up of insulated laminations to cut down on eddy currents induced in the core, which is an unwanted power-loss.
What are circular currents called?
If you are referring to currents in iron cores, circular currents are called eddy currents.
Can eddy current only exist in conductive or nonconductive materials?
'Eddy currents' are a circulating currents set up as a result of voltages induced into a metal component which not intended to carry current. For example, eddy currents are induced into the silicon-steel core of a transformer due to voltages induced into the core by the changing currents in the transformer's windings. Eddy currents are unavoidable, although steps can be taken to minimise them -in the case of a transformer's core, by manufacturing the core from laminations. Eddy currents generally have no useful function, but represent energy losses. To answer your question directly, eddy currents can only exist in conducting materials.
Why is transformer made of a number of iron sheets?
That is to reduce eddy currents, and therefore, transformer losses - since the eddy currents are wasted energy.
What has the author J A Tegopoulos written?
J. A. Tegopoulos has written: 'Eddy currents in linear conducting media' -- subject(s): Eddy currents (Electric)
What are the application of eddy current?
Eddy currents are usually unwanted (I can't think of a case where they are good), so there is no application for them. They are a nuisance that is mitigated through various means - cooling, very thin laminations, use of non-metalic clamps, etc.
What are the swirling currents called that are induced in transformers and produce heat losses?
Eddy currents
How do eddy currents affect falling objects?
Assuming the eddy currents are caused by the object falling through a magnetic field, the energy for the eddy currents come from the movement through the magnetic field. Therefore, simply due to energy conservation, the object should be slowed down.
What is the need of lamination in transformer?
The laminated plates prevent eddy currents from forming and thus creating unwanted magnetic flux which would counter the flux needed to induce the electric current in the secondary coil
