The present invention is to provide an induction type automatic-controlled fluid faucet, especially referring to a water faucet with completely brand new electromagnetic valve structure and automatic control circuit, which is characteristically comprising said electromagnetic valve device constituted by an iron-core consisted of a magnetic iron-core with a threaded non-magnetic iron core, and an engaged movable valve stem, which is equipped in the control valve and is wrapped on the exterior with several sets of polar plate, connected to a permanent magnet in series for each set of polar plate. The movable valve stem is attracted in the state of water-discharging due to the function of electromagnetic effects and is continuously attracted by the permanent magnet so as to avoid the usage of power and to prolong the service life of battery and to ensure the stable actuation of the movable valve stem while shielding (waving the hand) in front of the emission amplifier. And then the movable valve stem is going to be restored to the original "Shut the water flow" state while repeating the shielding action. A reset circuit is provided on the automatic control circuit device to ensure the movable valve stem to be able to secure in the "Shut the water flow" state at the beginning stage. A rapid-response circuit is preferably installed in the water-discharging controller so as to save the consumption of power during the water-discharging period. As a result, the present invention is indeed very economical and practical.
