Question Text
Question 1 :
The magnetic moment is a vector quantity whose direction is from south pole to north pole.
Question 2 :
Assertion: The magnetic poles of earth do not coincide with the geographic poles.
Reason: The discrepancy between the orientation of a compass and true north-south direction is known as magnetic declination.
Question 3 :
Assertion (A): Poles of a magnet can never be separated.<br>Reason (R) : Since, each atom of a magnetic material is a magnet in itself.
Question 6 :
At $45^o$ to the magnetic meridian , apparent dip is $30^o$. Find true dip :<br/>
Question 8 :
The angle of dip at a place horizontal and vertical components of earth's magnetic field are equal, is :<br/>
Question 10 :
Angle of dip at a place is $60^0$ and earth's magnetic field is $8\mu T$. Its horizontal component $B_H$ is :

Question 14 :
Angle of dip at a place is $30^0 $. If the vertical component of earth's magnetic field at that point is $7.5\times 10^{-5}T$. then the total magnetic field of earth at that point will be :
Question 15 :
Consider a short magnetic dipole of magnetic length $10 cm$. Its geometric length is
