Dip Needle
Original price was: $ 17.90.$ 17.82Current price is: $ 17.82.
A Dip Needle is a finely balanced magnetic needle used to measure the magnetic dip or inclination angle of the Earth’s magnetic field. Mounted to pivot freely in a vertical plane, the needle aligns itself with the Earth’s magnetic field lines, enabling precise determination of the angle between the horizontal plane and magnetic field direction. Dip Needles are essential instruments in geophysics, navigation, and laboratory studies of magnetism. They provide crucial data for mapping magnetic variations, compass calibration, and educational demonstrations. Typically constructed with magnetized steel or alloy, dip needles are designed for sensitivity and durability in field and lab environments.
