The thermal energy generated in the loop is zero. This is because the wire is not experiencing any resistance, which is necessary for the generation of thermal energy through the Joule heating effect. The problem statement does not mention anything about the presence of a current or a circuit in the wire, which means that no current is flowing through the wire when it is placed in the magnetic field. Hence, there is no resistance, and no thermal energy is generated.
