Two coils ‘P’ and ‘Q’ are separated by some distance. When a current of 3A 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 2A passes through ‘Q’, the flux through ‘P’ is:
  • a)
    6.67 × 10–4 Wb
  • b)
    3.67 × 10–3 Wb
  • c)
    6.67 × 10–3 Wb
  • d)
    3.67 × 10–4 Wb
Correct answer is option 'A'. Can you explain this answer?

Explanation:

Given:
Current through coil P, I1 = 3A
Magnetic flux through coil Q when current passes through coil P, Φ1 = 10^-3 Wb
Current through coil Q, I2 = 2A

We know that the magnetic flux passing through a coil is given by the equation:

Φ = μ₀NIA / l

Where:
Φ is the magnetic flux
μ₀ is the permeability of free space (constant)
N is the number of turns in the coil
I is the current passing through the coil
A is the area of the coil
l is the length of the coil

1. Magnetic flux through coil Q when current passes through coil P:

Φ1 = μ₀NI1A / l

2. Magnetic flux through coil P when current passes through coil Q:

Φ2 = μ₀NI2A / l

To find the magnetic flux through coil P when no current passes through it (I1 = 0), we can rearrange the equation as follows:

Φ2 = Φ1 * (I2 / I1)

Substituting the given values:

Φ2 = (10^-3 Wb) * (2A / 3A)

Simplifying:

Φ2 = 20 / 30 * 10^-3 Wb

Φ2 = 2/3 * 10^-3 Wb

Φ2 = 6.67 × 10^-4 Wb

Therefore, the magnetic flux through coil P when no current passes through it is 6.67 × 10^-4 Wb, which corresponds to option A.
