Electric Field & Coulomb's Law

Place two charges and visualise their field and the force between them.

Dipole in a Uniform Field

A dipole feels a torque τ = pE sinθ that twists it to line up with the field.

Field of an Electric Dipole

Compare the dipole's field on its axial and equatorial lines (2kp/r³ vs kp/r³).
