Abstract:
     A mutual-inductor, exhibiting two coils mutual inductance changes by changes of positions in electrical experiments of higher educational institutions, mainly used for reducing commercial power voltage by a transformer. After commutating filtration, it is used as a 555 time-base integrated circuit power, of which the output alternating voltage feeds power to the primary coil, and then the secondary coil linkages at the axial center of the primary coil; by adjusting the distance of the two coils by a screw fixed to the secondary coil, and observing a voltmeter and a milliammeter connected to the secondary coil, it shows the effect of the distance changing on producing induced voltage and current.
