Two coil '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. 6.67 × 10 –3 Wb
2. 3.67 × 10 –4 Wb
3. 6.67 × 10 –4 Wb
4. 3.67 × 10 –3 Wb

Correct answer: 6.67 × 10 –4 Wb
