Q10 of 54 Page 275

Can the dip at a place be (a) zero (b) 90°?

Dip is the angle made by the magnetic field lines of earth with the horizontal


a) Yes, As the magnetic field lines at the equator of earth is horizontal, the dip is 0°


b) Yes, As the magnetic field lines at poles of earth is vertical, the dip is 90°


The angle of Dip can vary from 0° to 90°

Magnetic scalar potential is defined as


Apply this equation to a closed curve enclosing a long straight wire. The RHS of the above equation is then –μ0i by Ampere’s law. We see that even when . Can we have a magnetic scalar potential in this case?

Can the earth’s magnetic field be vertical at a place? What will happen to a freely suspended magnet at such a place? What is the value of dip here?

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?
