2. Variation at the equator is ....??
Options:
a)180E/W
b)45E/W
c)0degrees
d)Less than 90degrees
Well, the correct option was
d) Less than 90degrees..
The reason is that, on the magnetic equator you cannot be certain on getting the variation as 45E/W at all times or you cannot have the variation on every point on the ME to be 0 and also no point on the ME falls between the True North and Magnetic North, so no point can have 180E/W
Hence the answer...
Cheers!
Answer is (c) 0 Degrees. Because the horizontal component on earth's magnetic field is at its strongest and so the magnetic compass is very stable and accurate. Hence variation at Magnetic Equator is 0 deg.
