A method for assembling a coil assembly, comprising a plurality of annular coils (10), comprises mounting each of the coils (10) in a respective jig (12), selecting one of the coils for alignment, energising the selected coil, and detecting alignment of a magnetic field produced by the selected coil with a nominal magnet axis (A). The selected coil is then moved to a new position by tilting and/or rotating and/or displacing it to improve alignment between the magnetic field produced by the selected coil and the nominal magnet axis. A hardening filler material (24) may be caused or permitted to harden between the selected coil and an adjacent coil to define a separation between the coils. A corresponding apparatus comprises a jig apparatus comprising a plurality of jigs defining a nominal magnet axis (A), actuators to rotate and translate the jigs, sensors for detecting the magnetic field generated by a coil and control means for driving the actuators. |
