🔍 Key Concepts

• Electromagnetic induction and how changing magnetic fields create currents • The idea that induced currents can oppose the change that created them • Which named "laws" in the options are specifically about induced currents and magnetic fields, not general electromagnetics or circuits

💭 Think About

• Which of these names is directly associated with the principle that an induced current acts to oppose the change in magnetic flux that caused it? • Think about where you study this effect: in transformers, generators, and moving conductors in magnetic fields—what specific law do you apply there? • Can you recall which of these laws is often stated as a verbal rule describing the direction of induced current or induced electromotive force (EMF)?

✅ Before You Answer

• Match the description: "opposes the original magnetic field" with the formal wording of the law you remember from physics/electrical theory • Eliminate options that are mainly about general electromagnetic equations or circuit theorems rather than the direction of induced current • Double-check which person’s name is linked in your notes/book to induced EMF direction in coils and conductors moving in a magnetic field
