O it is a noncontact force

the masses are tiny compared to the earth

Explanation:

Gravity force is calculated :

Fg=G*m1*m2/r²

gavitational force depends on: Mass of objects and their distance

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.
