Choose the correct option:
True dip is not mathematically related to apparent dip.
True dip is less than apparent dip.
True dip is always greater than the apparent dip.
True dip is always equal to apparent dip.
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 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 $\left.\tan 37^{\circ}=\frac{3}{4}\right)$
Angle of dip is $90^o$ at
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
Two bar magnets oscillate in a horizontal plane in earth's magnetic field with time periods of $3\,s$ and $4\,s$ respectively. If their moments of inertia are in the ratio of $3: 2$ then the ratio of their magnetic moments will e.
