TMR Solid-State Magnetic Sensor, Micro Sensor, SMA Probe (STJ-030) Helmholtz Coils n = number of turns

n = number of turns in a coil

Applying the Right Hand Rule

Enhancement from magnetic assembly: We have used electromagnetic finite element calculations in the design of the permanent magnetic assembly to achieve high field strength and uniform filed profile

linear and bipolar response

High quality soft iron C-frame construction for minimizing magnetic hysteresis

TMR Solid-State Magnetic Sensor, Micro Sensor, SMA Probe (STJ-030) Helmholtz Coils n = number of turnsThe STJ 030 is a low field magnetic sensor probe designed for magnetic imaging and scanning applications. The sensor probe features a Micro Magnetics SpinTJ sensor with an active (sensing) area of just a few microns (~0. 0001") in size. This allows the STJ 030 to detect field signatures from single magnetic particles or microscopic magnetic media. The field sensitivity of the STJ 030 is 5 nT, which is ten thousand times smaller than the magnetic field
