a : the process by which an electrical conductor becomes electrified when near a charged body, by which a magnetizable body becomes magnetized when in a magnetic field or in the magnetic flux set up by a magnetomotive force, or by which an electromotive force is produced in a circuit by varying the magnetic field linked with the circuit
b : the inspiration of the fuel-air charge from the carburetor into the combustion chamber of an internal combustion engine
c : the process by which the fate of embryonic cells is determined (as by the action of adjacent cells) and morphogenetic differentiation brought about
