	A dip circle is at right angle to the magnetic meridian. What will be the apparent dip
	A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from the centre of the magnet
	In two separate experiments the neutral points due to two small magnets are at a distance of $r$ and $2r$ in broad side-on position. The ratio of their magnetic moments will be
	The magnetic field due to the earth is closely equivalent to that due to
	The earth's magnetic field at a certain place has a horizontal component 0.3 Gauss and the total strength 0.5 Gauss. The angle of dip is
	The value of the horizontal component of the earth's magnetic field and angle of dip are $1.8 \times {10^{ - 5}}Weber/{m^2}$ and 30° respectively at some place. The total intensity of earth's magnetic field at that place will be
	When the N-pole of a bar magnet points towards the south and S-pole towards the north, the null points are at the
	Lines which represent places of constant angle of dip are called
	The vertical component of the earth's magnetic field is zero at a place where the angle of dip is
	At a certain place, the horizontal component ${B_0}$ and the vertical component ${V_0}$ of the earth's magnetic field are equal in magnitude. The total intensity at the place will be
