| Excessive torques may lead to demagnetisation or a breakage of the motor shaft. |
| Secolit gripper magnets are especially suitable for direct use in spot-welding machines, as no demagnetisation occurs. |
| This demagnetisation he detected by means of the movement of the needle of a magnetometer placed near one end of the iron wire. |
| Excessive torques lead to a break of the motor shaft or demagnetisation. |
| The resistance to demagnetisation in an external magnetic field is also relatively low. |
