Neodymium Discs and Polarity

APPH12-BM5KWL

A teacher uses a stack of six neodymium disk magnets for a demonstration. The stack of magnets causes strong deflection of a compass needle, as shown in the diagram.

What can be properly said about the polarity of the individual neodymium magnets?

A

The three magnets closest to the compass have only south polarity.

B

The three magnets closest to the compass have only north polarity.

C

All six magnets have only south polarity.

D

All magnets have both north and south polarity, but the south poles are aligned on the side closest to the compass.
