The constant magnetic field magnetic conductive slide block power transformation apparatus comprises a magnetic conductive slide block, a traction mechanism, an air gap, an induction coil, an excitation coil, an induction working magnetic circuit, a magnetic conductive bypass and a magnetic circuit. The magnetic conductive slide block is positioned in the air gap, and is driven by the traction mechanism to move in a reciprocating mode in the air gap. The induction coil winds around the induction working magnetic circuit. The excitation coil winds around the magnetic circuit and is connected with a direct current power supply. A sectional area of the induction working magnetic circuit is equal to a sectional area of the magnetic circuit. A sectional area of the magnetic conductive bypass is also equal to a sectional area of the magnetic circuit. The two ends of the induction working magnetic circuit are in parallel connection with the two ends of the magnetic conductive bypass; one pair of the ends which are in parallel connection form an air gap end surface, and the other pair of the ends which are in parallel connection are connected with the magnetic circuit. According to the apparatus, through the changing of a period of reciprocating motions of the magnetic conductive slide block, a frequency of an alternating current in the induction coil can be changed.
