Geographical meridian : A vertical plane passing through a place and geographic north and south axis is called geographic meridian. The direction to which the needle points is called magnetic north and the vertical plane through this direction is called the magnetic meridian. If the vertical plane in which the needle moves is rotated through an angle a to the magnetic meridian, then the needle will dip by an angle (a) 9 (b) a (c) more thane (d) less than θ. THANKS. OJASWI OJASWI ANSWER. A vertical plane passing through the magnetic axis of the freely suspended magnet is called magnetic meridian. MAGNETIC MERIDIAN IS A VERTICAL PLANE. If the vertical plane in which dip is $\theta_{1}$ subtends an angle $\alpha$ with meridian than other vertical plane in which dip is $\theta_{2}$ and is perpendicular to first will make an angle of $90-\alpha$ with magnetic meridian. v) Magnetic Meridian at any place is a vertical plane passing through the magnetic north and south poles of the earth. A vertical plane passing through the magnetic equator of the freely suspended magnet is called equatorial meridian. The horizontal component of the earth's magnetic field at the place is known to be 0.4 G. Determine the magnitude of the earth's magnetic field at the place. iv) Magnetic Axis is a straight line passing through the magnetic poles of the earth. A magnetic needle free to rotate in a vertical parallel to the magnetic meridian has its north tip down at 60° with the horizontal. … Magnetic Needle: It is a magnet tapered towards both ends and pivoted at the centre. (e) Magnetic Meridian (MM) : (i) It is a vertical plane at any place which passing through magnetic axis of the earth. A dip needle arranged to move freely in the magnetic meridian dips by an angle 6. The vertical plane that passes through the point at which the observer (instrument) is situated and that contains the vector of the geomagnetic field intensity at this point is called the plane of the magnetic meridian. a - point b - horizontal plane c - vertical plane d - line along N-S 1 See answer Shoaib1307 is waiting for your help. New questions in Physics. Magnetic Equator : An imaginary line, right bisecting the effective length of a magnet is called magnetic equator. A vertical plane at a place passing through magnetic north and south poles of the earth is called the magnetic meridian at that place. A needle perfectly balanced about a horizontal axis (before being magnetized), so placed that it can swing freely in the plane of the magnetic meridian… Question 100 Magnetic meridian is an imaginary A) line along north-south B) point C) vertical plane D) horizontal plane Answer: line along north-south Check Answer and Solution for above questio (ii) It is a vertical plane at any place which passing through axis of free suspended bar magnet or magetic needle. Magnetic meridian is a ? The great circle on the surface of the earth, in a plane perpendicular to the magnetic axis, is called the magnetic equator. It is inclined to Geographic Axis nearly at an angle of 17°. Magnetic meridian is (A) a point (B) a line along north-south (C) a horizontal plane (D) a vertical plane.
