Abstract
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 coil () is applied onto the circumferential surface () of the iron core (). An intermediate layer is made of an electrically insulating material, which is disposed between the circumferential surface () and the coil (). A protective layer () encapsulates the coil (). At least the pole surface () of the iron core () is made of a hard material and abuts the circumferential surface () in a lower region of the iron core (). The protective layer () contains a section () made of an elastic material in a region adjacent to the circumferential surface ().
