Which of the following statements about a ferromagnetic material is correct? It
- A. has a high susceptibility.
- B. attracts non-magnetic materials.
- C. has low relative permeability.
- D. repels other magnetic materials.
Correct Answer: A. has a high susceptibility.
Explanation
Ferromagnetic materials are characterized by having a high susceptibility, which means they are strongly attracted to magnetic fields. When placed in a magnetic field, ferromagnetic materials become magnetized and can themselves exhibit strong magnetic properties, attracting other magnetic materials. Ferromagnetic materials, such as iron, nickel, and cobalt, are commonly used in the construction of permanent magnets and electromagnets due to their strong response to magnetic fields.
