At a place, the horizontal and vertical intensities of earth's magnetic field is $0.30$ Gauss and $0.173$ Gauss respectively. The angle of dip at this place is.....$^o$
$30$
$90$
$60$
$45$
Dip angle are $30^o$ and $45^o$ at two different places, then ratio of horizontal component of earth magnetic field at these place will be
A magnetic needle is placed on a cork floating in a still lake in the northern hemisphere. Does the needle together with the cork move towards the north of the lake
A neutral point is obtained at the centre of a vertical circular coil carrying current. The angle between the plane of the coil and the magnetic meridian is.......$^o$
The angle of dip is the angle
What are the Earth magnetic elements defined ? And which are they ?
