Which property of a conductive material affects the amplitude of induced eddy currents?

The amplitude of induced eddy currents in a conductive material is influenced by several properties, which include electrical resistance, magnetic permeability, and temperature. Each of these properties plays a significant role in determining how eddy currents are generated and how they behave within the material.

Electrical resistance affects eddy currents by limiting the flow of electrical current. Higher resistance results in lower current amplitude, while lower resistance allows for greater current flow. As eddy currents circulate, the resistance of the material will cause energy losses in the form of heat, thereby impacting the overall amplitude.

Magnetic permeability is another crucial factor since it indicates how easily a material can become magnetized in the presence of a magnetic field. Materials with high magnetic permeability can support stronger magnetic fields, which enhances the generation of eddy currents. An increase in permeability generally leads to an increase in amplitude due to more efficient coupling of magnetic fields within the material.

Temperature influences both resistance and magnetic properties. As temperature increases, the electrical resistance of a conductive material usually increases, which can diminish the amplitude of eddy currents. Conversely, in some materials, temperature changes can alter magnetic permeability, further affecting how eddy currents are induced and how they flow.

Given that all these factors can impact the amplitude of induced eddy
