When a foreign body with iron properties, such as iron filings, enters the needle region, the magnetic field environment will change. And then cause the fluctuation of the instantaneous current of the magnetic field.The sensed abnormal current is transmitted to the control circuit board,and compare with the sensitivity.When the current value of this change reaches or exceeds the value of the detector sensitivity,The control circuit board will make alarm for the machine to stop, rewind belt and a series of instructions.And finally complete this series of actions.
