ABSTRACT:
A magnetic detector for detecting the magnetic field of a magnetic field generating substance including an even number of saturable coils aligned in a straight line with the distance between adjacent ones larger than the width of the magnetic field generating substance. The saturable coils are separated into at least two pairs, and a high frequency oscillator is provided to supply a high frequency voltage through a resistor circuit to each pair of the saturable coils. A rectifying voltages circuit is arranged across the resistors in a differential manner as an output. When the magnetic field generating substance is displaced over an interval wider than the width thereof relative to the saturable coils, the magnetic detector generates a linear output voltage.
