Explain what it means when we say a substance is magnetic. Discuss the relationship between electric and magnetic fields.

Which types of wires (cooper, aluminum, or string) are ferromagnetic metals?

See the explanation.

Explanation:

When we say a substance is magnetic it means the atoms are lined in a way that created a magnetic field that goes from one side to the other

These are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. This is the relationship.

Copper isn't ferromagnetic,

Aluminum isn't ferromagnetic,

String does have a ferromagnetic property

option number c is the right answer.
