Electromagnetic Induction question

2019 · 9 Apr · Shift 2 · Q70

JEE MainPhysicsElectromagnetic InductionMCQ+4 / −1
Two coils 'P' and 'Q' are separated by some distance. When a current of 3 A flows through coil 'P', a magnetic flux of 10–3 Wb passes through 'Q'. No current is passed through 'Q'. When no current passes through 'P' and a current of 2 A passes through 'Q', the flux through 'P' is :-
  1. A
    3.67 × 10–4 Wb
  2. B
    3.67 × 10–3 Wb
  3. C
    6.67 × 10–4 Wb
  4. D
    6.67 × 10–3 Wb
