Subject: CALIBRATION AND CONSTRUCTION OF HELMHOLTZ COILS
All
I would like to construct a Helmholtz coil to perform magnetic field
immunity testing at DC frequencies and thus simulate the effect of a
permanent magnet. There are some details on construction in EN61000-4-8
which details power frequency magnetic field immunity testing within the
scope of the EMC directive. However the fields referred to are measured in
A/m, whereas I need a field of, for example, 5mTesla.
Can anybody advise me as to how to construct such a coil with a test volume
of 0.5 x 0.5 x 0.5m and a field of 5mTesla?
Thanks
Ian Gordon
