Physics Electricity and Magnetism on STEM Calculators is a set of interactive electricity and magnetism calculators built to support problem solving from high school physics through AP/IB and introductory university E&M. It helps you compute key quantities fast while still understanding the physics behind the formulas with clear, structured outputs.
This subject covers core electrostatics and electric fields (Coulomb’s law, charge interactions, electric field strength, electric potential, potential energy), capacitors and energy storage, and fundamentals of electric circuits such as Ohm’s law, resistors in series/parallel, power in circuits, and Kirchhoff-style circuit analysis for multi-loop problems.
On the magnetism side, you’ll find tools for magnetic fields and forces (Lorentz force on moving charges, force on current-carrying wires), field sources like long straight wires, loops, and solenoids using standard E&M relationships, and practical computations that connect current, field strength, and geometry.
The chapter set also extends into electromagnetic induction and AC concepts, including Faraday’s law, Lenz’s law direction reasoning, induced EMF, flux changes, and common AC circuit relationships and electromagnetic wave fundamentals where applicable. Difficulty ranges from beginner-friendly numeric practice to advanced multi-step setups typical of exam and university-style questions.
Students can verify homework and build confidence, teachers can generate examples and demonstrate concepts quickly, self-learners can follow consistent methods without getting stuck on algebra, and advanced users can speed up repeated calculations for labs and engineering-style workflows. Use this page to input known values, compute unknowns reliably, and deepen your understanding of electricity, magnetism, induction, and circuit behavior.
