Answer

Brief Explanations:

The strength of an electromagnet is affected by the amount of current (more current, stronger magnet), the number of coils (more coils, stronger magnet), and the material of the core (ferromagnetic materials enhance strength). The direction of current affects the polarity, not strength, and the wire - material mainly affects resistance and current flow but not directly the magnet's strength as much as the other factors mentioned.

Answer:

B. the amount of current flowing through the wire C. the number of coils in the wire E. the material of the core
