Creating or manifesting the electromagnetic field is the solution he came up with as the product of the perfect fusion of the trinity of wood, lightning, and divine sense.
To be exact, his idea is to convert his divine sense into a tool capable of controlling an electromagnetic field. The electromagnetic field will be produced in his foundation while his divine sense controls it.
He doesn't think he will have any problems achieving this because he knows about electromagnetic induction. He intends to use this theory to convert the electricity in his life seeds into a magnetic field that his divine sense can control by using his divine sense to cause a flux in the electric field of his life seeds.
In his past life, humans used the theory of electromagnetic induction to produce electricity by moving a conductor in a magnetic field. This is a process of converting mechanical energy into electricity. What he intends to do is reverse it.
