摘要： A method of actuating a well tool can include displacing a magnetic device pattern in the well, thereby transmitting a corresponding magnetic signal to the well tool, and the well tool actuating in response to detection of the magnetic signal. A method of injecting fluid into selected ones of multiple zones penetrated by a wellbore can include displacing at least one magnetic device into at least one valve in the wellbore, the valve actuating in response to the displacing step, and injecting the fluid through the valve and into at least one of the zones associated with the valve. An injection valve for use in a subterranean well can include a sensor which detects a magnetic field, and an actuator which opens the injection valve in response to detection of at least one predetermined magnetic signal by the sensor.
