ABSTRACT: In this research,
measurement of static magnetic induction and magnetic moment induced by HP was
carried out. The measurement of static magnetic induction was done for two
directions namely horizontal and vertical directions. The static magnetic
induction induced by that HP was measured using Pasco Magnetic Probe. The
effect of the thickness of material such as cooper (Cu) inserting between
magnetic probe and the HP was studied. For the horizontal direction (x
direction), Cu and without Cu between magnetic probe and the HP, then the magnetic induction was measured for
the distance of 0,7 cm from the HP. Static magnetic induction was also measured
in vertical direction (z-direction) with and without Cu. The results showed
that the static magnetic induction induced by that HP has a normal distribution
with the position of the peak near the top of the HP. The value of magnetic
induction was found to be 10 x10-4 T and
9 x 10-4 T without and with Cu
respectively. For vertical measurement, the static magnetic induction reduced
its values with increasing distance from the HP. By plotting B versus distance
it was obtained that the magnetic moment of the HP was 1,5 Am2. Based on these
plots then it was also found that the level of absorption of about 0,02 mm-1.
