But perhaps the most important field expedient tool is the one between your ears. Think before you improvise and be careful about improvising. It is sometimes better to accept having to make a trip to the store to get the right tool than to use the wrong tool wrongly and end up with a problem worse than the one you started with!. . .
OK 4 attempts and honestly, I tried to do it the same each time..682" ball used. Disregarding the high load (it seemed the same), there is still over 10gr;. difference.
Thus, the magnetic field follows the shape of a nonmonotonic function. For the developed methodology, a socalled Thermal Modifier ((TM=f(T))) is introduced in the analytical model in order to update the superficial field strength ((H_s(T)=Hs_{T0} cdot TM)), as can be seen in the flowchart presented in Fig. 4. A nonlinear leastsquare fit ...
