Answer
Less than
Work Step by Step
The magnetic flux is given as $\phi=BAcos\theta $
When the normal to the loop points horizontally, then the angle between the field and the normal to the loop is $90^{\circ}$. Thus, $\phi_H=BAcos90^{\circ}$
$\phi_H=0$
Similarly, when the normal to the loop points vertically, then the angle between the magnetic field and the normal to the loop is $0^{\circ}$; hence, the flux is
$\phi_V=BAcos0^{\circ}$
$\phi_V=BA $
Thus, the magnetic flux when the loop points horizontally is less than the magnetic flux when the loop points vertically downward.
