Can the dip at a place be (a) zero (b) `90^@`?

The angle of dip at a place where horizontal and vertical components of earth's magnetic field a equal is

A dip circle shows an apparent dip of 60^@ at a place where the true dip is 45^@ . If the dip circle is rotated through 90^@ , what apparent dip will it show?

Angle of dip at a place, wher horizontal and verical componet of earth's fiedl are qual is

A compass needle oscillates 20 times per minute at a place where the dip is 45^@ and 30 times per minute where the dip is 30^@ . Compare the total magnetic field due to the earth at the two places.

The vertical component of Earth's magnetic field at a place is equal to the horizontal component. What is the value of angle of dip at this place ?

The vertical component of Earth's magnetic field at a place is equal to the horizontal component. What is the value of angle of dip at this place ?

The horizontal component of earth's magnetic field at a place is 3.6 xx 10^(-5) T. if the angle of dip at this place is 60^(@) , the vertical components of earth's field at this place is
