    • In an actuating apparatus applicable to an actuation of a valve installed in an intake air passage of an internal combustion engine, a first magnetic circuit (D.sub.1) is formed with a stationary member (A) and with a part of a driven member (B), the driven member being disposed within the stationary member so as to be linearly or angularly displaced, and a second magnetic circuit (D.sub.2) is formed in the stationary member and another part of the driven member so as to be branched from the first magnetic circuit, a strength of a magnetic flux flowing through the second magnetic circuit being the same as that of a magnetic flux flowing through the first magnetic circuit and a direction of the magnetic flux flowing through the second magnetic circuit being opposite to that of the magnetic flux flowing through the first magnetic circuit. Under the condition described above, at least one new magnetic flux is generated by means of electromagnetic coil(s), a direction of the new magnetic flux being such that the magnetic flux flowing through either of the first or second magnetic circuit is strengthened and that flowing through the other of the first or second magnetic circuit is weakened so that the driven member is linearly or angularly displaced at a position at which strengths of both magnetic fluxes flowing through the first and second magnetic circuits become again balanced.
