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?

What is the horizontal component of Earth's magnetic field? If the horizontal and vertical components of Earth's magnetic field are equal then what is the angle of dip?

The ratio of the vertical component to the horizontal component of earth's magnetic field at a place is 1 . What is the angle of dip at that place ?

The horizontal component of the earth's magnetic field at any place is 0.36 xx 10^(-4) Wb m^(-2) If the angle of dip at that place is 60 ^@ then the value of the vertical component of earth's magnetic field will be ( in Wb m^(-2))

The vartical component of the earth's magnetic field is zero at a place where the angle of dip is
