'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.

What characteristic exists in magnets that does not exist in materials that that lack magnetism?
Domains are aligned.
What is universal solvent?
A universal solvent doesn't exist; water is a good solvent for many materials.
Can a static magnetic field exist in a good conductor?
A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.
Which ofthe materials exist in solid and liquid states?
Materials that can exist in both solid and liquid states are primarily classified as phase-change materials, such as water (ice and liquid water) and certain metals like gallium and mercury. These materials undergo phase transitions based on temperature changes, allowing them to coexist in multiple states. Additionally, some polymers can exhibit both solid and liquid behaviors depending on temperature and pressure conditions.
What is the source of gemstones metals and other materials used to make products?
Gemstones are natural products extracted from mines.But now some materials can be artificially produced; also imitations exist.
What footwear may be designed to be electrically conductive or non-conductive?
Footwear designed to be electrically conductive typically includes materials like leather, rubber, or specific types of plastics. Non-conductive footwear is often made of materials such as PVC or rubber with insulating properties to prevent electrical currents from passing through. Both types are important for safety in environments where static electricity or electrical hazards exist.
Is einsteinium conductive?
All the metals conduct electricity; but no determined data exist today for einsteinium.
Why can't an electric current exist if the circuit is broken?
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
Can diffusion current and drift current can exist in a Semi conductors?
Yes.
What is a single negative electric charge that contributes virtually no mass to an atom?
electron ,Believe it is called a FREE electron. Because it is not internally bound to the nucleolus of the atom. in a conductive material , like copper, they are free to drift from one atom to another. if it was not for free electron's ,electricty(current) could not exist.
Why is there a magnetic field even when there is no current?
A magnetic field can exist without current due to the intrinsic magnetic properties of particles like electrons. In atoms and materials, the alignment of these particles' spins can create a magnetic field. This is known as magnetism and is responsible for phenomena like the Earth's magnetic field.
In a current carrying conductor what exist around it?
a magnetic field
How is conventional current used if it doesn't exist?
For no bloody reason!
Do alethiometers exist?
Alethiometers, as featured in Philip Pullman's "His Dark Materials" series, are fictional devices and do not exist in reality. Their concept is a product of the author's imagination.
Difference between intrinsic and extrinsic materials?
Intrinsic materials are found within an area. Extrinsic materials do not exist within, and must be located outside of the area.
What stores materials to make ribososomes in a cell?
They are in the nucleolus. They exist as two parts
What characteristic exists in magnets that does not exist in materials that that lack magnetism?
