Just use a comparator to measure the difference between the sensor and a reference voltage. This is then fed into the coil to power it. Amazing that it is stable this is due to a slight phase lead in the hall effect sensor and the non-linear characteristics of the coil.
switching whit a hall effect sensor when the magnet is near the magnetic coil?????
explain me please
