Abstract
A controllable emitter of an irrigation apparatus including a drip line having pressurized fluid therein is provided. The controllable emitter includes a container coupled to the drip line, the container being formed to define an interior and including an inlet through which the pressurized fluid is receivable in the interior from the drip line and an outlet through which the pressurized fluid is exhaustible from the interior, a magnetic stopper, which is normally disposable in a first position such that the magnetic stopper prevents a flow of the pressurized fluid through the outlet and which is actively disposable in a second position such that the magnetic stopper permits the flow and a controllable actuator configured to generate a magnetic field operable to urge the magnetic stopper to move from the first position to the second position.
