Electric Dipole Field
Two opposite charges. The electric field between them is not a diagram — it is the gradient of the scalar potential, computed and drawn from the equations. This is what that field actually looks like.

YOUR TURN
Your turn. Ask Claude to write a Manim scene for an electric quadrupole — four charges in a square arrangement. Then ask it to vary the charge signs and watch how the field topology changes. The field is always E equals negative del phi — the code is the proof.

Introduction
[0:00] Two opposite charges, the electric field between them is not a diagram. It is the gradient of the scalar potential computed and drawn from the equations. This is what that field actually looks like. The electric dipole. Two opposite charges, field lines leave the positive charge and terminate on the negative. The spacing between lines encodes the field magnitude. Tighter spacing means stronger field. This is not an artist's impression. It is E equals negative gradient of phi drawn from the equations. What the animation shows, the field is completely determined by the charge positions. Flip the sign of one charge and every line reverses. The pattern is the potential gradient made visible. The field is the negative gradient of the scalar potential. E equals negative del phi. Compute phi from Coulomb superposition, differentiate, draw the result. No approximation.
Verdict
[0:51] Two opposite charges, the field is the gradient of the scalar potential. E equals negative del phi. Field lines show direction, spacing shows magnitude. The animation is the field, not a diagram of it. Your turn. Ask Claude to
Your Turn
[1:05] Write a man I'm seeing for an electric quadrupole. Four charges in a square arrangement. Then ask it to vary the charge signs and watch how the field topology changes. The field is always E equals negative del phi. The code is the proof. Lay them in for bare.
