- What are Maxwell's equations in point (differential) form and how are they derived? In one line Maxwell's four equations in point form are nabla·D = ρ , nabla·B = 0 , nabla×E = -∂B/∂ t and nabla×H = J + ∂D/∂ t , describing e... 1
- What are Maxwell's equations in integral form and what does each one mean physically? In one line In integral form, Maxwell's equations relate the flux of D and B through closed surfaces, and the circulation of E and H around... 1
- Why are Maxwell's equations significant and what is the role of displacement current? In one line Maxwell's equations unify electricity, magnetism and light into one theory, and Maxwell's displacement current term made them co... 1
- What is the gradient of a scalar field and what is its physical meaning? In one line The gradient of a scalar field is a vector that points in the direction in which the field increases fastest, and its magnitude... 1
