The magnetic poles of the earth would change places

Scientists have realized that during the last 200 years the north and south poles have weakened and throughout those years the displacement has already reached a speed of 48 kilometers per year, it is known by evidence that the earth's magnetic field has about 4 one billion years and during 2.6 million years the poles have exchanged at least 10 times, the last time that happened was 780 thousand years ago, so scientists believe that we are already in the face of the next magnetic pole shift.
