This course explores capacitors, electric current, and magnetism, providing a deep understanding of electromagnetic principles. It starts with the fundamentals of capacitors, including their construction, capacitance, problems, circuits, energy storage, and the effect of dielectrics. Students learn how capacitors behave in series and parallel arrangements and how to calculate stored energy.
Next, the course introduces electric current and current density, covering the flow of charge, Ohm’s law, and real-world applications in circuits. It then moves to magnetism, explaining magnetic fields and the forces exerted on moving charges and current-carrying wires. Concepts such as the magnetic force on orbiting charges, magnetic confinement, the Earth’s aurora, and magnetic torque on loops are clearly illustrated.
With step-by-step derivations, problem-solving strategies, and practical examples, learners develop a solid grasp of the interactions between electric and magnetic fields. By the end of the course, students are equipped to analyze and solve complex problems in electromagnetism and understand the operation of devices like electric motors and magnetic confinement systems.
