Magnetic reversal
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
The magnetic axis is relatively unstable compared to the rotational axis. The magnetic poles move around quite a bit from decade to decade. In fact, geologists have discovered that the alignment of the molecules in some sedimentary materials shows that the north and south magnetic poles actually switch places every few tens of thousands of years.

Scientists do not know the answer to this question.

This is known as magnetic reversal when earth's magnetic poles change places.

No. Der
In early 2014, scientists have discovered that the Earth's magnetic field has been weakening for some time. This could eventually lead to the switching of the Earth's magnetic poles.
because of earths tilt (axis)different amounts of sunlight hit different places at different times that's the answer
As such till now there is no proper or valid theory to prove or explain the cause of earth's magnetic field. A bar magnet or a magnetic compass alligns itself in the direction of earth's magnetic field. This process happens as south pole of magnet alligns itself to north pole of earth n vice versa true north pole is southpole of magnet. Exact location of places can be done by calculating the magnetic flux density n various other factor . . . . . .

Because the metals in the hot center of our earth are moving arround.

There are many places one can purchase magnetic beads. Some of them include Magnetic Beads, Kaleidoscope Crafts, Magnetic Jewelry, Arizona Bead Company, and Amazon.
