Suppose that two objects attract each other with a gravitational force of 32 newtons. if the distance between the two objects is doubled, what is the force of attraction between them? a) 8 n b) 16 n c) 32 n d) 64 n

b would be the answer

where is the

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.
