Yes it should be.Because our body has its own certain electro-magnetic fields.There should be certain effect on physiology by sleeping in direction with earth magnetic field. === === No. There is no evidence that a human can detect or react to the earth's magnetic field, so it makes no difference which direction you lie in when you sleep.
Because the magnetic north points vertically downwards.
from south to north
The magnetic poles of a compass needle are named after the directions in which they point. 'Magnetic North' and 'Magnetic South' are LOCATIONS (used to distinguish them from 'True North' and 'Magnetic North'), and do NOT describe their magnetic polarities. As 'unlike poles attract', the north pole of the compass needle points towards Magnetic North, whose polarity must, therefore, be south. By extension, the polarity of Magnetic South is north.
yes it is pointless
The Earths magnetic field is always shifting
Magnetic Reversal
The Earth's magnetic field is called the Magnetosphere. Loops of magnetic energy coupling the north and south pole that trap energetic subatomic particles are called the Van Allen belt.
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.

No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

The geographical North and South Pole - not the magnetic poles.
Yes it can reverse from North to South
idontknow
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
Compasses use the magnetic field to navigate always pointing North.
