A) while taking reading of tangent galvanometer, the plane of the coil must be set at right angles to the earth's magnetic meridian
B) a short magnet is used in a tangent galvanometer since a long magnet would be heavy and may not easily move
C) measurements with the tangent galvanometer will be more accurate, when the deflection is around \[{{45}^{o}}\]
D) a tangent galvanometer can not be used in the polar region
