Dipole Calculator


Imagine electric charges doing the tango, where equal and opposite charges elegantly waltz together, creating a beautiful dipole. It’s like the Fred Astaire and Ginger Rogers of the electric world!

Dipole Formula

Dipole Moment (p) = Charge (q) x Separation (d)

Here’s the electrifying formula for calculating a dipole’s moment, where p is the dipole moment, q is the charge, and d is the separation. Now, let’s dance our way through dipole knowledge!

Categories of Dipole Calculations

Category Types Range Dipoles Results Interpretation
Electric Dipole Point Dipole, Any Dipole Moment (p) Electric Field, Potential Energy
Extended Dipole
Magnetic Dipole Magnetic Monopole, Any Magnetic Moment (μ) Magnetic Field, Torque
