2. Which of the following sentences is correct? A magnet has a positive pole and a negative pole. Opposite poles attract and like poles repel. An object whose particles are pointing in different directions has a ferromagnetic effect. An object that does not respond naturally to magnets whose molecules a grouped in pairs and cancel each other out has a diamagnetic effect.

Answer 1

The correct sentence is: "Opposite poles attract and like poles repel."Explanation:- A magnet has a north pole and a south pole, not a positive pole and a negative pole.- Opposite poles (north and south) attract each other, while like poles (north and north or south and south) repel each other.- The ferromagnetic effect refers to the phenomenon where certain materials, such as iron, become strongly magnetized in the presence of a magnetic field.- Diamagnetic materials are those that do not respond naturally to magnets and have molecules that are grouped in pairs and cancel each other out.
