The angle of dip is the angle
A current carrying coil is placed with its axis perpendicular to $N-S$ direction. Let horizontal component of earth's magnetic field be $H_0$ and magnetic field inside the loop be $H$. If a magnet is suspended inside the loop, it makes angle $\theta $ with $H$. Then $\theta =$
The magnetic field due to the earth is closely equivalent to that due to
A dip circle is at right angle to the magnetic meridian. What will be the apparent dip......$^o$
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
