When the plane of the coil is normal to the magnetic meridian, a neutral point is observed at the centre of the coil. A magnetic field is directed perpendicular to the plane of a circular coil of area 0.2 m² and 250 turns. If BH = 0.314 × 10^-4 T , the current in the coil is : Real dip theta=40.9^@ Let the vertical component of earth's magnetic field be V and its horizontal component at magnetic meridian be H. Then the angle of dip theta at magnetic meridian will be given by tantheta=V/H..... When the dip needle is suspended at an angle of 30^@ to the earth magnetic meridian then it makes an angle 45^@ with the horizontal. perpendicular to geographic axis of Earth. A dip needle vibrates in the vertical plane perpendicular to the magnetic meridian. A magnetic needle free to rotate about the vertical direction (compass ) point west of the geographic north . A voltage measured perpendicular to the plane is indicative of the CME of hot electrons. The horizontal component of the earth’s magnetic field at the place is known to be 0.35 G. Determine the magnitude of the earth’s magnetic field at … Maharashtra State Board HSC Science (Electronics) 11th. The time period of vibration is found to be 2 seconds. The electron follows a circular path of radius R. In a time, t, the electron travels halfway around the circle. A dip circle is taken to geomagnetic equator. For a vertical plane other than magnetic meridian $\alpha>0$ or $\cos \alpha<1$ so $\theta^{\prime}>\theta$ In a vertical plane other than magnetic meridian angle of dip is more than in magnetic meridian. The needle will stay (a) in horizontal direction only (b) in vertical direction only (c) in any direction except vertical and horizontal (d) in the direction it is released The needle is allowed to move in a vertical plane perpendicular to the magnetic meridian. The box is then rotated through 90 o position on the horizontal circular scale. An electron with charge -e and mass m travels at a speed v in a plane perpendicular to a magnetic field of magnitude B. The magnitude of the horizontal component of the earth ' magnetic field at the place is known to be . A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 22° with the horizontal. Magnetic meridian is the plane . This sets the needle and vertical scale exactly in magnetic meridian. A magnetic field B is applied perpendicular to the plane of the sample. Click hereto get an answer to your question ️ A vertical circular coil of radius 0.1 m and having 10 turns carries a steady current. East of this agonic line, the magnetic North Pole is to the west of the geographic North Pole and a correction must be applied to a compass indication to get a true direction. To get the true heading, you need to first read the magnetic compass, then either add an Easterly, or subtract a Westerly, magnetic variation; based on the isogonic lines. Another magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at with the horizontal . Then the angle of dip is (a) 0° (b) 30° (c) 45° (d) 90° Illustration of a thin-film CME measurement geometry in the presence of a strong in-plane electric field (E). passing through the magnetic axis of Earth. What is the amount of work done by the magnetic field? Here the needle and vertical scale are in a plane perpendicular to the magnetic meridian. Textbook Solutions 6926. Reuse & Permissions × Important Solutions 17 ... perpendicular to the magnetic axis of Earth. The same needle is then allowed to vibrate in the horizontal plane and the time period is again found to be 2 sec. The same needle is then allowed to vibrate in the horizontal plane and the time period is again found to be 2 seconds. The time period of vibration is found to be 2 sec. If the magnetic field is increased from 0.01 T to 0.06 T during a time interval of … A dip needle vibrates in the vertical plane perpendicular to the magnetic meridian.
