Abstract

A magnetic actuator, which is used particularly for devices of internal combustion engines, includes a magnetic coil and at least one ferromagnetic component. In this instance, a magnetic flux caused by the magnetic coil is able to be guided via the component. On ferromagnetic component, a magnetic choke point is provided, which is used to adjust the magnetic flux. The magnetic choke point may be formed by a local microstructural modification of a ferromagnetic material of the ferromagnetic component. Furthermore, a valve having such a magnetic actuator and a method for producing such a magnetic actuator are indicated.
