An iron rod is subjected to cycles of magnetisation at the rate of `50Hz`. Given the density of the rod is `8xx10^(3)kg//m^(3)` and specific heat is `0.11xx10^(-3)calxxkg^(@)C`. The rise in temperature per minute, if the area enclosed by the `B-H` loop corresponds to energy of `10^(-2)J` is (Assume there is no radiation losses)
