Why would placing two very strong magnets in the middle of two seperate balloons provide a good model for nuclear fusion?

Question

A. Some nuclei repel each other and some attract each other, just like two sides of a magnet.
B. The nucleus is very large compared to the rest of the atom, just like the balloon surrounding the magnet.
C. The positive charges of the nuclei make it difficult for the nuclei to join, just like the balloons keep the magnets apart.

Answer 1

A. Some nuclei repel each other and some attract each other, just like two sides of a magnet.

When it comes to nuclear fusion, the nuclei of atoms come into play. Similar to magnets, some nuclei repel each other due to electromagnetic forces, while others can attract each other. By placing two strong magnets in the middle of two separate balloons, this model demonstrates the repulsion and attraction forces of nuclei during nuclear fusion.
