Eddy currents cannot be induced in which material?

Eddy currents are loops of electric current that are induced within conductors by a changing magnetic field due to Faraday’s law of electromagnetic induction. Materials that are good electrical conductors, such as aluminum, steel, and copper, readily allow the flow of these induced currents. On the other hand, materials that are insulators, like latex paint, do not support the flow of electric current.

Latex paint is primarily composed of polymers and is designed to act as an insulating barrier. It possesses high resistance to electric current, preventing any eddy currents from being induced when exposed to a changing magnetic field. This insulating property makes latex paint incapable of enabling eddy currents, thereby confirming it as the correct choice in this context.

In contrast, materials like aluminum, steel, and copper are conductive and would readily allow eddy currents to form under the influence of a changing magnetic environment.
