A magnet pole for magnetic levitation vehicles includes an iron core having an upper pole surface, a lower contact surface for a magnet rear side and a circumferential surface disposed between the pole surface and the contact surface. A plurality of microwells are within the well, and a first common fluid volume is within the well above the microwells. A flexible connecting strip is interposed between and is integrally connected to the bottom cover and the right wall so as to permit turning of the bottom cover relative to the right wall to an open position, in which the bottom opening is exposed so as to facilitate replacement of terminals in the housing.
