Question

magnet makes an angle of 45 degree with the horizontal in a plane making an angle of 30 degree with the magnetic meridian find the true value of dip angle at the place​

Answer 1

Answer:

The true value of angle of dip at the place is 40.9 degree

Explanation:

Let the actual angle of dip is $\phi$

now we have horizontal components are related as

$(B_{net}cos\phi)cos30 = B cos45$

Vertical components are related as

$(B_{net} sin\phi) = B sin45$

now we will divide the two equations

$\frac{tan\phi}{cos30} = tan45$

so we have

$tan\phi = tan45 cos30$

$\phi = tan^{-1}(\frac{\sqrt3}{2})$

$\phi = 40.9$ degree
