title: Positioning device for magnetically sensitive environments.
abstract: Presented in this short communication are design principles for the construction of a positioning apparatus for biological specimens in magnetically sensitive environments. An apparatus with 3 degrees of freedom was built and found to provide position accuracy to within +/- 0.25 mm throughout a cubic volume measuring 9 cm on each side.
