PERUBAHAN KUAT MEDAN MAGNET SEBAGAI FUNGSI JUMLAH LILITAN PADA KUMPARAN HELMHOLTZ
Abstract: Design and study of
Helmholtz coils have been carried out. The coils diameter was designed of about
13 cm and number of turns of 50, 100, 150, 200 and 250. Magnetic field that
produced by those coils was measured using pasco magnetic probe PS-2162 as a
function of an applied current, distances and number of turns. As comparison,
then the magnetic field produced by these coils had been compared to the
standard one. Maximum value of magnetic field was obtained at the center of the
coil. For an applied current of 2 A, then the magnetic field at the center of
the coils either standard one or the designed one was 7.156 x 10-5T and 5.907 x
10-5T respectively. The value of magnetic field increases as number of turns
and current are increased, for the coils with number of turns of 50 and 250
that carrying current of 1.0 A produced a magnetic field of 5.241 x 10-5T and
6.208 x 10-5T respectively. This is due to the direct relationship between
current (I) and number of turns (N) against magnetic field as expected. The
value of magnetic field decreases as moving away from the center of coil either
in horizontal or vertical direction.
