Square Induction Coil FESP 5210-1
The square induction coil FESP 5210-1 is used to generate magnetic fields for immunity testing according to IEC 61000-4-8, IEC 61000-4-9 and IEC 61000-4-10. The edge length of the square shaped coil is 1 m. The coil comes with wing terminals, which allow a versatile and simple connection to the current source.
Operation as Helmholtz Coil:
Two square induction coil FESP 5210-1 can be combined to form a Helmholtz coil pair. The main advantages of a Helmholtz coil pair is an increase of fieldstrength and a significant improve- ment of field uniformity. For this purpose the coil planes are aligned in parallel. Electrically the coils have to be wired in series, keeping in mind that the current through the coils must flow in the same direction. This is very important to obtain the wanted addition of both fieldstrength contributions in the volume between the coils.
