A circular loop carrying a current is replaced by an equivalent magnetic dipole. A point on the loop is in

Any point on the equatorial line of a bar magnet (or a magnetic dipole) is called as a point at “Broadside-on position”. So, when the current carrying circular loop is replaced with a magnetic dipole, the point on the loop comes at the equatorial position, Thus the point is said to be located at broadside-on position.

The reduction factor K of a tangent galvanometer is written on the instrument. The manual says that the current is obtained by multiplying this factor to tan θ. The procedure works well at Bhuwaneshwar. Will the procedure work if the instrument is taken to Nepal? If there is some error, can it be corrected by correcting the manual or the instrument will have to be taken back to the factory?
