Question

which of the following statements are true about magnetic field sources? choose all that apply
□ opposite poles repel each other
□ they have a north and a south pole
□ opposite poles attract each other
□ they have an east and west pole

Explanation:

1. For the statement "opposite poles repel each other": In magnetism, opposite poles (north - south) attract, like poles repel. So this is false.
2. For the statement "they have a north and a south pole": Magnets have a north and a south pole, this is a fundamental property of magnets. So this is true.
3. For the statement "opposite poles attract each other": This is a basic rule of magnetism, opposite magnetic poles (north - south) attract. So this is true.
4. For the statement "they have an east and west pole": Magnets have north - south poles, not east - west poles. So this is false.

Answer:

• $\square$ opposite poles repel each other (false)
• $\square$ they have a north and a south pole (true)
• $\square$ opposite poles attract each other (true)
• $\square$ they have an east and west pole (false)

The correct options to check are "they have a north and a south pole" and "opposite poles attract each other".
