The north pole of one magnet attracts the south pole of another magnet. The needle of a compass is itself a magnet; the end of the needle that points north is capped with an arrow and often painted red. A typical compass with a red, arrow-capped needle pointing near due north. In light of this, explain why the arrow‑capped end of a compass needle is attracted to the North Pole of the Earth.

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.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
