calibration, which calibration xD,
the only real part about calibration was that it asked " suggest was the probe calibrated correctly for 3 marks?"

just use the equation given to find b(in milli tesla using the give equation) use there given value, find percentage difference and give a comment like how 1.2% is really insignificant and can account of r practical error, imo the trick was to use n as number of turns PER METER!

Really? I got a really big number!! Damn now I really feel bad!

hey dont fret over that, just think logically .. water is 1000 kg per m3... and i got a metal wire as 1.2 kg per damn m3 .... . naturally the correct answer is some 7000 kg per m3 or along that tune,

no point over spoilt milk :biggrin:

Guys, i'd advise you to stop talking about the exam..since we're not actually allowed. If a Mod sees this, we're all going to get warned.

yeah either lucky or unlucky your call, though i would prefer to get them done a.s.a.p, there were like what 3 whole question of percentage diff or uncertainties!
