The space around a charge in which its electric Web3.3 Electrostatics. We see that Faraday’s law in the static limit is. ∇ × E = 0 (3.3) One way to satisfy the above is to let E = −∇Φ because of the identity ∇ × ∇ = 0. 4 Alternatively, one can assume that E is a constant. But we usually are interested in solutions that vanish at infinity, and hence, the latter is not a viable ... disney dreamlight valley how to catch an eel
