Working Principle
A Dip Needle works by allowing a magnetic needle to rotate freely around its support. When users hold the device vertically, the needle aligns with the Earth’s magnetic field and shows the dip angle on the scale. When placed horizontally, it behaves like a compass and points toward magnetic north. The non-magnetic support reduces friction and interference, so the needle moves smoothly and shows accurate readings.
