Dip Circle

Whatsapp Order

A Dip Circle is a precision scientific instrument used for measuring the magnetic dip or inclination angle of the Earth’s magnetic field at a specific location. It consists of a magnetic needle or dip needle mounted on a graduated circular scale, which can rotate freely in the vertical plane. The instrument allows geologists, physicists, and surveyors to determine the angle between the horizontal plane and the Earth’s magnetic field lines, an important parameter in geomagnetic studies and navigation. Dip circles are commonly employed in academic research, mineral exploration, and educational demonstrations to analyze variations in Earth’s magnetism and assist in directional orientation.
