Question

The reason the north pole of a bar magnet at the equator that is free to rotate points north is because the south geographic pole of the earth is the earth's magnetic south pole. there is a net accumulation of negative magnetic charge at the earth's south geographic pole. there is a net accumulation of positive magnetic charge at the earth's north geographic pole. the north geographic pole of the earth is the earth's magnetic north pole. the north geographic pole of the earth is the earth's magnetic south pole. What is the value of Bvector . ds for the path shown in the figure here? 16 i 10 i 4 i 2 i -2 i -4 i -10 i -16 i

Explanation / Answer

(e) North geoghraphic pole of magnet is earth's south magnetic pole

(c)

Total current enclosed = 2i + 5i + 3i - ( 4i + 2i)

= 4 i
