i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.

1. metals

2. metalloids only

3. nonmetals only

4. metals and metalloids

5. metalloids and nonmetals

i just took this assignment so this is correct
