1. An alignment device comprising:
a coil configured to generate an induced voltage from a magnetic field, or an electrode configured to generate an induced voltage from an electric field, the coil or electrode forming part of a field detection unit (FDU); and
a comparator configured to compare the induced voltage to a threshold voltage and activate an indicator based on the comparison,
wherein the alignment device comprises a plurality of FDUs, each FDU comprising an individual coil configured to generate an induced voltage from a magnetic field, or an individual electrode configured to generate an induced voltage from an electric field, and
wherein each FDU is identical.
