Coulomb Force Control (クーロン力制御) is a Release Type magic that exerts control over the Coulomb Force, making the electromagnetic repulsion within a field to be lowered to 1/10,000th. The electromagnetic force among nuclei of deuterium atoms is about 1036. When that electromagnetic force is lowered to 1/10,000th, the effect of gravity becomes 100 times greater than normal, although this is still not enough to enable nuclear fusion. However, if ionization provides enough thermal energy, a spontaneous nuclear fusion reaction may occur.
