In the magnetic meridian of a certain place, the horizontal component of the earth’s magnetic field is $0.26\;G$ and the dip angle is $60^o$. What is the magnetic field of the earth at this location?
$0.52\; G$
$0.26\; G$
$0.13\; G$
$0.86\; G$
The pole near the geographic north pole is called ...... . The pole near the geographic south pole is called ...... .
A dip circle lies initially in the magnetic meridian, it shows an angle of dip $\delta$ at a place. The dip circle is rotated through an angle $\alpha$ in the horizontal plane and then it shows an angle of dip $\delta^{\prime}$. Hence $\frac{\tan \delta^{\prime}}{\tan \delta}$ is
At a place, if the earth's horizontal and vertical components of magnetic fields are equal, then the angle of dip will be.......$^o$
A dip needle in a plane perpendicular to magnetic meridian will remain
A magnet is placed horizontally on ground with its north pole towards the geographic north pole of the earth. The neutral point is obtained
