What happens when current flows and eddy currents are produced?

When current flows through a conductor, it can create a magnetic field around it. If this magnetic field changes over time or if there are conductive materials present that experience the influence of the magnetic field, eddy currents may be induced. Eddy currents are loops of electrical current that circulate within the conductor, often leading to energy being lost in the form of heat due to the resistance of the material.

In the context of the question, when eddy currents are produced, they do not contribute effectively to the net flow of current in the system; instead, they cause a dissipation of energy. This energy loss results in an overall decrease in the efficient distribution of usable current across the conductors. Therefore, as eddy currents create heat and lead to losses, the overall distribution of current effectively decreases.

Options that remark on the core cooling down or resistance changes are not accurately aligned with the direct consequences of eddy currents. When eddy currents are induced, there is usually an increase in temperature rather than cooling, and while resistance can be understood to change in some scenarios, especially due to temperature effects, it does not directly reflect the implications of current flow and eddy currents as described.

Thus, the answer indicating that the overall distribution of current decreases captures the adverse
