Magnetic Effects of Current · JEE PhysicsClass 12
Real weightage, real PYQs, and an honest measure of how ready you are in this chapter.
How much is Magnetic Effects of Current actually worth?
Every chapter's weight on ViJEEta is derived, not asserted: we tag every previous-year JEE Main question to its chapter, and a chapter's weight is its real share of those papers. Magnetic Effects of Current carries 4.9 of 100 Physics marks. Your readiness /300 uses exactly this weight — so an hour spent here moves your score by what the exam actually pays for it.
What does "mastered" mean here — honestly?
ViJEEta refuses to print a number it hasn't measured. Magnetic Effects of Current shows "—" until you've answered at least 3 questions in it. After that, mastery is a guessing-corrected IRT true score at a conservative ability estimate over the chapter's real item difficulties — a blind 25% MCQ guess earns zero. Reading theory caps evidence at 0.60, unproctored practice at 0.75; "mastered" (≥0.80) is reachable only through tests. That's why the number is worth trusting.
