Keywords: Bioeffects & Magnetic Fields, Magnets (B0), Halbach
Motivation: Magnetic field effects on cellular metabolism have been documented but with little to no exploration of that space with respect to field direction, strength, and oscillation frequency.
Goal(s): Our goal is to design a custom electromagnet that integrates with a fluorescence microscope to study magnetic field effects on cellular metabolism.
Approach: We developed and characterized a rotating electromagnetic Halbach cylinder along with custom amplifier circuitry and software.
Results: Generation of a homogeneous field (2% variation) in an arbitrary direction over a 12 mm x 12 mm region in the x-y plane (perpendicular to the fluorescent light path) is demonstrated.
Impact: The electromagnetic Halbach array produces a controllable and homogeneous field orthogonal to a fluorescent light source, allowing for further investigation of magnetic field effects on cellular metabolism.
