I am in fact working on this, using an 0604 SMD UV LED array. Printing the PCB for this requires significant initial effort but once done it can make copies easily.
The basic idea is to print out coil arrays on single sided PCB stock then stack the PCBs to create the required field strength.
Magnets are tricky but there are motors (AC induction comes to mind) which just need an iron core.
see http://4hv.org for more details.
