DIP NEEDLE
APPARATUS
dip needle
202-20-F
DESCRIPTION
Large demonstration dip needle shows
inclination
of earth's magnetic field. Use needle as a compass to find the
direction
of the horizontal component of the earth's field. Then orient dip
needle vertically so that it lies in the north-south plane.
It would appear from the 1995
USGS magnetic field charts, that in northeast Ohio the earth's
magnetic
field strength is about 56 uT
at an inclination of about 70°.
