A method of actuating a well tool can include producing a magnetic 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
A method of actuating a well tool can include producing a magnetic 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 can include producing a magnetic pattern in a tubular string having multiple injection valves interconnected therein, actuating a set of at least one of the injection valves in response to the magnetic pattern producing, producing another magnetic pattern in the tubular string, and actuating another set of at least one of the injection valves in response to the second magnetic pattern producing.

1. A method of injecting fluid into selected ones of multiple zones penetrated by a wellbore, the method comprising: displacing at least one first magnetic device in the wellbore;after a predetermined spacing in time, displacing at least one second magnetic device in the wellbore;a valve actuating in response to the predetermined spacing in time between the displacing of the first and second magnetic devices, the actuating comprising piercing a pressure barrier; andinjecting the fluid through the valve and into at least one of the zones associated with the valve. 2. The method of claim 1, wherein the displacing at least one first magnetic device further comprises displacing a predetermined number of the first magnetic devices in the wellbore. 3. The method of claim 1, wherein the displacing at least one second magnetic device further comprises displacing a predetermined number of the second magnetic devices in the wellbore. 4. The method of claim 1, wherein a sensor of the valve detects a magnetic field. 5. The method of claim 1, wherein a sensor of the valve detects a change in a magnetic field. 6. A method of actuating at least one well tool in a well, the method comprising: producing a first magnetic pattern in the well, thereby transmitting a corresponding first magnetic signal to the well tool, wherein the first magnetic pattern comprises a predetermined spacing in time between displacement of first and second magnetic devices in the well; andthe well tool actuating in response to detection of the first magnetic signal. 7. The method of claim 6, wherein the actuating comprises piercing a pressure barrier. 8. The method of claim 6, wherein the first pattern comprises a predetermined spacing in time between predetermined numbers of magnetic devices. 9. The method of claim 6, wherein the at least one well tool comprises multiple well tools, and wherein a first well tool actuates in response to detection of the first magnetic signal. 10. The method of claim 9, wherein a second well tool actuates in response to detection of a second magnetic signal. 11. The method of claim 10, wherein the second magnetic signal corresponds to a second magnetic pattern produced in the well, and wherein the second magnetic pattern comprises a predetermined spacing in time between displacement of third and fourth magnetic devices in the well. 12. The method of claim 6, wherein the well tool comprises a valve. 13. The method of claim 12, wherein the valve comprises an injection valve. 14. The method of claim 13, further comprising injecting fluid outward through the injection valve and into a formation surrounding a wellbore. 15. The method of claim 6, further comprising detecting the first magnetic signal with a magnetic sensor. 16. The method of claim 15, wherein the magnetic sensor comprises an inductive sensor. 17. A method of injecting fluid into selected ones of multiple zones penetrated by a wellbore, the method comprising: producing a first magnetic pattern in a tubular string having multiple injection valves interconnected therein, wherein the first magnetic pattern comprises a predetermined spacing in time between displacement of first and second magnetic devices in the wellbore;actuating a first injection valve in response to the first magnetic pattern producing;producing a second magnetic pattern in the tubular string, wherein the second magnetic pattern comprises a predetermined spacing in time between displacement of third and fourth magnetic devices in the wellbore; andactuating a second injection valve in response to the second magnetic pattern producing. 18. The method of claim 17, wherein the first magnetic pattern comprises a predetermined spacing in time between displacement of predetermined numbers of the first and second magnetic devices. 19. The method of claim 17, wherein the second magnetic pattern comprises a predetermined spacing in time between displacement of predetermined numbers of the third and fourth magnetic devices. 20. The method of claim 17, wherein the first injection valve actuates in response to at least one first sensor detecting the first magnetic pattern. 21. The method of claim 17, wherein the second injection valve actuates in response to at least one second sensor detecting the second magnetic pattern.
