Magnetic Stimulation Accessories CatalogueMagProbeProbe for magnetic field evaluationMagProbe is designed to provide informationabout the magnetic field from stimulatingcoils. The probe is useful as a simple tool forestimating the suitability of a specific coil,intended for a specific application. Inaddition, the probe enables the user to predictthe ability to stimulate at different locations intissue, when using different coil positions.MagProbe provides a quantitative measure ofthe field gradient and the peak magnetic fieldamplitude. The MagProbe output isproportional to the magnetic field change withtime (dB/dt). The change in the magnetic fieldwith time induces a proportional voltage intissue. This voltage generates a current, theamplitude of which is depending on theconductivity of the tissue and bone structure.This is the current that can stimulate the nerveand muscle fibers.MagProbe (BNC); with a standard BNCconnector for easy usage with an oscilloscope.2 different types of MagProbes are available.MagProbe (DIN); with a standard DINconnector for easy usage with EMG/EPequipment.Technical Data for MagProbe (DIN)Connector5p DIN plugCable length3 mLoop wireø2.8mm CU.Loop inside diameter 20mm.Output voltage 1 mV per 1 kT/s.Accuracy ±10%Approx. peakCorrection factors20kHz 1.210kHz 1.45kHz 1.8Ordering Number 9016E031-Technical Data for MagProbe (BNC)ConnectorBNC plugCable length3 mLoop wireø2.8mm CU.Loop inside diameter 20mm.Output voltage 1 V per 2.6 kT/s.Accuracy ±10%Ordering Number 9016E033-38 www.MagVenture.com
