🧲 By the end of this lesson, you’ll be able to:

• Understand the core principles of magnetism:
  • Learn that magnetism arises from the motion of electric charges
  • Explore magnetic poles (north and south) and how opposite poles attract while like poles repel
  • Visualize magnetic field lines and how they represent the strength and direction of magnetic forces
• Discover how electricity creates magnetic fields:
  • Understand that a current-carrying wire generates a magnetic field around it
  • Explore electromagnets, which use coils of wire and electric current to produce controllable magnetic fields
  • Learn how increasing current or coil turns strengthens the magnetic field
• Explore applications of electromagnetism in technology, such as:
  • Electric motors – convert electrical energy into mechanical motion
  • Generators – convert mechanical motion into electrical energy
  • Transformers – regulate voltage in power systems
  • Magnetic levitation (maglev) trains – use electromagnetic forces for frictionless travel
  • MRI machines – use strong magnetic fields for medical imaging
• Understand the relationship between magnetic fields and electric currents:
  • Learn about Faraday’s Law of Electromagnetic Induction, which explains how changing magnetic fields can induce electric currents
  • Explore Lenz’s Law, which describes the direction of induced currents
  • Recognize how this interplay forms the basis of modern power generation and wireless charging
