Abstract
The present invention relates to a force application device for a control stick of an aircraft, wherein the control stick comprises a control lever () rotating a shaft (A) about a first axis (A), the device comprising a magnetic brake () which comprises a magnetisable element () mounted on the shaft and a magnetic transmitter () which is opposite the magnetisable element and free to rotate about the first axis relative to the magnetisable element, the magnetic transmitter having an activated state in which the magnetic transmitter is supplied with current and generates a magnetic field in a volume occupied by the magnetisable element, and a deactivated state in which the magnetic transmitter is not supplied with current and does not generate a magnetic field, so as to prevent the magnetisable element from rotating about the shaft relative to the magnetic transmitter.
