Micromagnetic stimulation (MS) is a promising branch of neurostimulation technologies. Microcoil (coil) based magnetic stimulation uses micrometer sized coils that generate a time-varying magnetic field which as per Faradays Laws of Electromagnetic Induction induces an electric field on a conductive surface. This method of stimulation has the advantage of not requiring electrical contact with tissue, however these coils are not easy to operate. Large currents are required to generate the required magnetic field. These currents are too large for standard test equipment to provide, and additional power amplifiers are needed. To aid in the development and application of micromagnetic stimulation devices, we have created a compact single unit test setup for driving these devices called the Coil Driver. This unit is designed to drive small inductive loads up to {+/-}8 V at 5 A and 10 kHz.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
