When discussing the earth's magnetic field we could say that the earth has a

geomagnetic north pole that is similar to the north pole of a magnet.

geomagnetic north pole that is similar to the south pole of a magnet.

magnetic core that has a charge similar to the south pole of a magnet.

random collection of magnetic poles dispersed in different locations.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
