Which of the following is a characteristic of nonmagnetic metals?

Nonmagnetic metals are defined by their lack of magnetic properties, which largely stems from their composition. They do not contain iron or have very low levels of iron, which is a primary element responsible for ferromagnetism. As a result, nonmagnetic metals cannot be magnetized. This characteristic distinguishes them from magnetic metals, such as steel or iron, which can be easily magnetized due to their crystalline structure and the presence of iron.

The other options suggest characteristics that are typical of ferromagnetic materials. Metals that contain high levels of iron or are ferrous can be magnetized due to their iron content. Therefore, these characteristics do not apply to nonmagnetic metals.
