A force that attracts or repels certain materials is called magnetism.

The force that attracts or repels certain materials is called magnetism.

To determine the answer to this question, you can rely on your knowledge of basic physics concepts or conduct a simple search. Magnetism is a fundamental property of certain materials, specifically those that contain magnetic substances like iron, cobalt, and nickel. These materials can exert forces on other magnetic objects, attracting or repelling them depending on their orientation. Taking note of these facts, you can conclude that magnetism is the most appropriate answer.
