Question

1. which of the following is true about poles on magnets?

north poles attract south poles.
north poles repel south poles.
north poles attract north poles.
both b and c are true.

1. based on the magnetic field lines shown, what is the orientation of the my

image of magnetic field lines with a magnet labeled n (red) and s on the left, and a mystery magnet on the right

Explanation:

For question 3: The fundamental rule of magnetism is that opposite magnetic poles attract, and like magnetic poles repel. North and south are opposite poles, so they attract; like poles (north-north, south-south) repel.
For question 4: Magnetic field lines always emerge from the north pole of a magnet and enter the south pole. Looking at the field lines between the known magnet and the mystery magnet, the lines connect the south pole of the known magnet to the near end of the mystery magnet, meaning the near end of the mystery magnet is a north pole, so the mystery magnet has its north pole facing the known magnet's south pole (orientation: North pole facing left, South pole facing right).

Answer:

1. North poles attract south poles.
2. The mystery magnet has its north pole oriented toward the south pole of the labeled magnet (left end is North, right end is South).
