All synthetic materials ultimately come from natural resources. organic matter. minerals. fossil fuels.

it is actually natural resources

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.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
