Provided is an electrical apparatus comprising a magnetic core, a conductive coil wound around at least a part of the core, a cooling element configured to receive a cooling fluid to cool the core and the coil during operation, and at least one biasing element operatively associated with the core to urge the core and the coil into engagement with the cooling element despite differential expansion or contraction of the core and the coil and manufacturing tolerances. Further provided is a method for making an electrical apparatus comprising disposing a conductive coil wound around at least a part of a magnetic core, disposing a cooling element between the core and the coil, the cooling element configured to receive a cooling fluid to cool the core and the coil during operation, and urging the core and the coil into engagement with the cooling element despite differential expansion or contraction of the core and the coil and manufacturing tolerances.
