Magnetic forces are the strange ones: they act only on moving charge, always at right angles, via \( F = qvB\sin\theta \). That geometry is why charged particles circle in magnetic fields. Practice free below with multiple choice (MCQ) questions and quizzes, graded instantly.
Right-hand rules do the heavy lifting here. Currents make fields (wrap your fingers), fields push currents (palm push), and Ampere's law handles the symmetric cases.
