Electromagnetism Calculator

Calculate electric field, electric potential, magnetic field, and basic circuit values with interactive charts and step-by-step outputs.

Use Cases

  • - Electrostatics and magnetostatics homework checks
  • - Circuit quick calculations for series and parallel loads
  • - Unit comparison between SI and CGS conventions
  • - Rapid sanity checks before deeper simulation work

Formulas Used

  • E = kq / r^2
  • V = kq / r
  • B = mu0 * I / (2pi r)
  • Ohm Law: I = V / R and P = I^2 R
