When 2 smaller nuclei are forced closer together, so they fuse to make a larger nucleus, releasing lots of energy. 1 of 5 What is a disadvantage of nuclear fusion? Requires a large electric current( so nuclei have enough kinetic energy to fuse. 2 of 5 What is another disadvantage of nuclear fusion? Requires a large magnetic field(to stop nuclei touching walls and losing energy. 3 of 5 What are 3 advantages of nuclear fusion? 1. Fuel(hydrogen) is free 2. Fuel is readily available in sea water 3. it is not radioactive 4 of 5 Where does nuclear fusion happen naturally? In stars 5 of 5
