At a certain location in Africa, a compass points $12^o$ West of the geographic North. The North tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points $60^o$ above the horizontal. The horizontal component of the earth's field is measured to be $0.16\, G$. The magnitude of the earth's field at the location will be
$0.23\times10^{-4}\, T$
$0.18\times10^{-4}\, T$
$0.32\times10^{-4}\, T$
$0.81\times10^{-4}\, T$
The relations amongst the three elements elements earth's magnettic fleld, namely horizontal component $H$, vertical component $V$ and dip $\delta$ are, $( B_{E}=$ total magnetic fleld)
A dip needle in a plane perpendicular to magnetic meridian will remain
A dip circle is at right angle to the magnetic meridian. What will be the apparent dip......$^o$
Lines which represent places of constant angle of dip are called
A magnet is placed horizontally on ground with its north pole towards the geographic north pole of the earth. The neutral point is obtained
