Dip Circle Geomagnetism Science Educational-Dip Angle Earth magnetic Field Study DESCRIPTION: The Dip Needle is a compass pivoted to move in the plane containing the magnetic field vector of the earth. It will then show the angle which the magnetic field makes with the vertical. Dip circle, also called Dip Needle, or Inclinometer, instrument for measuring the inclination, or dip, of the Earth’s magnetic field. It consists essentially of a magnetic needle pivoted at the centre of a graduated circle. The assembly is mounted such that the needle swings vertically rather than horizontally, as does a compass needle. When the instrument is placed with the plane of the circle in the magnetic meridian of the Earth, the needle points in the direction of the Earth’s magnetic field.Specification:All metal, standard make. The non magnetic cast metallic base is provided with three levelling screws. The horizontal base is graduated in 360 degrees. A vertical pillar with vernier moves smoothly on horizontal base. A vertical metallic case of cast aluminium with removable glass sides is fitted on the vertical pillar. The magnetic needle moves freely on Swiss cone bearings and is well balanced and magnetized; a sensitive spirit level is also provided.
