The angle of dip at a place on the earth gives
The horizontal component of the earth's magnetic field
The location of the geographic meridian
The vertical component of the earth's field
The direction of the earth's magnetic field
Explain angle of dip.
A bar magnet is situated on a table along east-west direction in the magnetic field of earth. The number of neutral points, where the magnetic field is zero, are
If the dip circle is set at $45^o$ to the magnetic meridian, then the apparent dip is $30^o$. The true dip. of the place is
The vertical component of the earth's magnetic field is $6 \times 10^{-5} T$ at any place where the angle of dip is $37^{\circ}$. The earth's resultant magnetic field at that place will be $\left(\right.$ Given $\left.\tan 37^{\circ}=\frac{3}{4}\right)$
A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through $180^o$ to deflect the magnet by $30^o$ from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through $ 270^o$ to deflect the magnet $30^o$ from magnetic meridian. The ratio of magnetic moments of magnets is
