Magnetic Dip Needle/compass

Show the angle of earth's magnetic field lines

Show the angle of earth's magnetic field lines; doubles as a large compass. Place the compass flat on the ground (a leg at the top folds out to keep it flat) and make note of the direction of the needle. Right the compass, and place it parallel to the field line. The needle will deflect, showing the direction of the Earth's magnetic field. Updated on 05/30/13
