I have to spec a sensor to monitor the magnetic field of a DC solenoid element.
The specification for the solenoid includes its length, DC resistance, current at the applied supply voltage, and most importantly, the expected Dipole Moment of the unit, as 42 Am^2.
I plan to attach a solid state linear Hall Effect sensor directly to one end during test, and am trying to estimate the field strength to select a sensor.
One family of sensors I'm looking at output a range of 2 ±2V with sensitivities of 0.5, 1.1, or 2.7 mV/Gauss, so approximate field ranges of ±5000, ±1818, or ±740 Gauss.
My problem is that I have no idea of what field strength in Gauss to equate to 42 Am^2
Can anyone help me solve this?
Thanks!
Dave
