Why is Jupiter so much larger than Earth? Check all that apply

Inner planets were created at higher velocities. Outer planets attracted helium, hydrogen, and other gasses and Gases escaped from inner planets and not from outer ones.

Explanation:

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.
