{"knowledge_schema": {"broad_category": "Physics \u2192 Electromagnetism \u2192 Maxwell's Equations", "refinement": "This problem examines the fundamental laws governing electric and magnetic fields, particularly in a hypothetical scenario where magnetic monopoles exist.", "specific_scope": "The focus is on identifying which Maxwell's equations would change if isolated magnetic poles (monopoles) were possible, affecting the relationships between electric and magnetic fields.", "goal": "Determine which specific Maxwell's equations would be altered in a universe with magnetic monopoles."}, "summary": "In this scenario, we are exploring how Maxwell's equations would be modified in a universe where magnetic monopoles exist, allowing for isolated North or South poles. The key changes would occur in the equations related to the circulation of the electric field and the divergence of the magnetic field, as these equations govern the behavior of electric and magnetic fields in relation to charges and currents. Understanding these modifications helps clarify the fundamental principles of electromagnetism in different theoretical contexts."}
