At the magnetic poles of the earth, a compass needle will be
Vertical
Bent slightly
Horizontal
Inclined at $45°$ to the horizontal
At a place, if the earth's horizontal and vertical components of magnetic fields are equal, then the angle of dip will be.......$^o$
The north pole of the earth's magnet is near the geographical
Dip angle in vertical plane at an angle ${\cos ^{ - 1}}\,\left( {\frac{1}{{\sqrt 2 }}} \right)$ from magnetic meridian is $60^o$, then actual dip at that place
The magnetic field due to the earth is closely equivalent to that due to
The pole near the geographic north pole is called ...... . The pole near the geographic south pole is called ...... .
