Let the magnetic field on earth be modelled by that of a point magnetic dipole at the centre of earth. The angle of dip at a point on the geographical equator

A

is always zero.

B

can be zero at specific points.

C

can be positive or negative

D

is bounded.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
On the magnetic equator, the angle of dip is always zero but on the geographical equator, the angle of dip is zero only at points where it intersects the magnetic equator. Also, on other points on the geographical equator, the angle of dip can be positive and negative. Since the two equators are inclined at a certain angle, the angle of dip will always lie within a range and hence, it is bounded.

Let r be the distance of a point on the axis of a magnetic dipole from its centre. The magnetic fiedl at such a point is proportional to

The earth's magnetic field is approximately like that of a giant magnetic dipole, whose axis is inclined roughly 20^@ west of the axis of rotation of earth which is the geographic N-S direction. The strength of earth's magnetic field is of the order of 10^-4 tesla . Three magnetic elements of earth are: Magnetic declination (theta) , magnetic inclination or magnetic dip (delta) and horizontal component (H) of earth's magnetic field. Magnetic declination is the small angle between magnetic axis and geographic axis at a place. Magnetic dip at a place is the angle, which the direction of total strength of earth's magnetic field (R) makes with a horizontal line in magnetic meridian. If H is horizontal component and V is vertical component of earth's magnetic field, then H=Rcos delta , V=Rsin delta and R=sqrt(H^2+V^2) . At a place on the surface of earth. H is of the order of 3*3xx10^-5tesla . At magnetic poles, a compass needle points out
