Products: SpinCoil-CTRL Helmholtz Coil Controlling Systems

SpinCoil-CTRL: General Description

Micro Magnetics' SpinCoil-CTRL enables an operator to generate an arbitrary magnetic field vector (Bx, By, and Bz) within the uniform space inside a 3-axis Helmholtz coil system. The magnetic field can be a stationary field pointing to any direction, or a linear/circular oscillating field. The operator can also generate any time dependence for the magnetic field. The system includes a 3-axis Helmholtz coil, three independent power supplies, a computer, and controlling software. It also includes a 3-axis magnetic sensor which can measure the earth field accurately. The system is capable of canceling the earth field inside the 3-axis Helmholtz coil. The controlling software is easy to use, and all functions can be accessed and executed on the Graphics User Interface (GUI). Both DC and AC magnetic fields can be generated. This package is ideally suited to calibrate magnetic sensors and to measure field-dependent properties of materials. It can be used for research and development of biomedical devices, microscopy, magnetic nanoparticles, electronic compasses, MRAMs, MEMS, magnetic shape memory alloys, near-field sensors, micro- and nano-robotics.
