1. A system for performing triage on an electronic apparatus, comprising:
a user interface configured to receive input of an electronic device model designator and output an inferred condition of the electronic device to a user;
a computer memory configured to hold one or more reference magnetic field patterns corresponding to the electronic device model;
a test platform configured to receive and support the electronic device;
one or more magnetic sensor arrays configured to detect a magnetic field strength and direction at each of a plurality of array locations proximate to an electronic device holding volume adjacent to the test platform; and
a microprocessor operatively coupled to the computer memory, the user interface, and the one or more magnetic sensor arrays, the microprocessor being configured to execute computer instructions to:
interrogate and receive the magnetic field strengths and directions from each of the plurality of magnetic sensors;
compare one or more received magnetic field patterns corresponding to the received magnetic field strengths and directions to the one or more reference magnetic field patterns corresponding to the electronic device model;
infer a condition of the electronic device by selecting a best fit between the one or more received magnetic field patterns and the one or more reference magnetic field patterns; and
output the inferred condition to the user via the user interface.
