The value of angle of dip at the earth's magnetic pole is -(A) 0°(B)(C) 90°(D)45°180° |
Answer» Let us begin with the definition of magnetic dip.Magnetic dip or magnetic inclination at a place is defined as the angle which the direction of the total strength of the earth’s magnetic field makes with horizontal line in magnetic meridian . It is represented by the symbol δ. Dip circle is the instrument used for measuring the value of magnetic dip. At different places on the surface of the earth δ is different. At the two magnetic poles, the magnetic needle rests vertically. Therefore , angle of dip at the two poles is 90°. On the magnetic equator, the angle of dip is 0 as the needle would rest horizontally at the magnetic equator. At other places the value of dip angle lies between 0 and 90 degrees. Therefore, the angle of dip from equator to the poles varies from 0° to 90°. (A) is correct option it is 90 degree, at the north poke and -90degree at the south pild option c 90° is the right answer (C)it's 90 ° at either pole north or south |
