(a)
The orientation of sheet for maximum magnitude of magnetic flux through it.
(a)
Explanation of Solution
Introduction
The magnetic flux can be defined as the number of magnetic field lines that pass through a closed surface.
The mathematical expression for the magnetic flux is given by,
The magnetic equator is a line on the surface of Earth on which magnetic field of Earth is horizontal. At the magnetic equator, for the maximum magnitude of the magnetic flux the orientation of the flat sheet should be in such a way that the normal to the sheet is vertical in orientation.
Conclusion:
Therefore, the orientation of sheet is in such a way that normal to the sheet is vertical.
(b)
The orientation of the flat sheet.

Explanation of Solution
Introduction:
The magnetic flux can be defined as the number of magnetic field lines that pass through a closed surface.
The mathematical expression for the magnetic flux is given by,
At the magnetic equator, for the minimum magnitude of the magnetic flux the orientation of the flat sheet should be in such a way that the plane of the paper is perpendicular to the surface of the Earth at that location.
Conclusion:
Therefore, the orientation of the sheet is perpendicular to the surface of the Earth at that location.
