Electromagnetic Induction starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Electromagnetic Induction. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A rectangular loop of wire is pulled with constant velocity out of a region of uniform magnetic field. What happens to the induced current in the loop as it leaves the field?
Describe the working principle of an electric generator based on electromagnetic induction.
Explain why the induced current in a coil opposes the change in magnetic flux through it.
Mutual induction occurs when:
State Faraday's first law of electromagnetic induction.
The induced emf in a circuit is given by the formula: emf = -dΦ/dt. What does the negative sign indicate?
