1. A collision-avoidance system for devices located in a magnetizing environment, comprising:
a first device, which comprises a control system, which in turn comprises a collision risk estimation module;
said collision risk estimation module being provided to estimate a likelihood of collision between the first device and a second device due to a force of magnetic attraction;
a monitoring module configured to generate at least one alarm command in response to a determination by the collision risk estimation module that the likelihood of collision exceeds at least one threshold value;
a control module configured to control the first device according to the alarm command;
a brake module via which the control module causes the first device to be braked in response to the alarm command;
an interaction module configured to receive a release command issued by a user and send the release command to the brake module when the first device is in a braked state,
said brake module being further configured to release the braked state of the first device according to the release command;
a timing module configured to start a timing of a delay period after release of the braked state of the first device;
in which the collision risk estimation module is configured to refrain from issuing the alarm command during the delay period and to direct the control module to automatically return the first device to the braked state at the end of the delay period in response to sensing by the collision risk estimation module that a current magnetic field intensity is greater than a first threshold value, indicating that the first device is in a position of being attracted to the second device at the end of the delay period.
