Detailed Solution

(A) is true. When a current flows through a machine made of iron, it induces a magnetic field. If this current is alternating, it leads to a changing magnetic flux in the iron. The changing magnetic flux, in turn, can induce eddy currents in the iron structure of the machine. Eddy currents are circulating currents that flow within conductive materials, like iron, in response to a changing magnetic field.

(R) is also true. According to Faraday's law of electromagnetic induction, a change in magnetic flux through an area induces an electromotive force (EMF) in any closed circuit within that area. The induced EMF can lead to the flow of eddy currents within the material.
