A decision block that checks the surrounding magnetic field strength using the built-in sensor.
If the proceed option is set to Immediately, then check the current magnetic field strength without pausing the fiber. If set to When changed, then the fiber will pause until the magnetic field strength comes within the microtesla range, or goes out of range.
If both minimum field strength and maximum field strength is set
and doesn’t evaluate to null then the field strength must be within the range.
If only minimum is set, then the field strength must be greater than or equal to it.
If only maximum is set, then the field strength must be less than or equal to it.
If neither minimum nor maximum is set, then the current field strength is just assigned to the current field strength variable without a check.
The magnetic field magnitude at the Earth’s surface ranges from 25 to 65 microteslas.
