Bartington Instruments is pleased to announce the release of a new Helmholtz coil, the HC16. This 350mm diameter coil is built on a non-conductive coil former and provides an aperture of 13.7 x 14cm.
The HC16, when driven by the PA1 Power Amplifier, generates a magnetic field of up to ±1mT from DC to 440Hz and >100μT at 5kHz. It is designed for testing small sensors at a higher amplitude and provides a homogeneous field to 1% in a volume of 1150cm3 and to 0.1% in 175cm3.
A mounting table is provided to hold the test item inside the central area.
Further details and a datasheet are available here.
