Magnets, Currents, and Magnetic Fields
Learning Time: 4-12 hours
Content: Magnets, Currents, and Magnetic Fields is a subject that examines the basic principles of magnetism and the magnetic effect of electric current. This subject covers magnetic field lines, Lorentz force, solenoids, and electromagnetic induction. The basic properties of magnets are emphasized in TYT, while the AYT focuses on electromagnetism and its applications. The current 2025 curriculum also covers topics such as magnetic resonance imaging (MRI) and renewable energy (generators). Learning this topic forms the basis for electromagnetic systems.
