Explanation:

Read the poem. excerpt from “Spring” by Christina Rossetti Frost-locked all the winter, Seeds, and roots, and ston CVes of fruits, What shall make their sap ascend That they may put forth shoots? Tips of tender green, Leaf, or blade, or sheath; Telling of the hidden life That breaks forth underneath, Life nursed in its grave by Death. Which line from the poem contributes most to a hopeful tone? "Telling of the hidden life" "Frost-locked all the winter," "Life nursed in its grave by Death." "What shall make their sap ascend

Given:

Current flowing in the loop= 5 A

Equation of circuit loop = y² + z² = 9

To find:

Magnetic field at point P (4 cm,0,0)

Solution:

Radius of the loop from the equation= 3 cm

We know that, magnetic field at the axis of a circular loop is:

B = μ₀/4π * 2πIR²/(R²+x²)^1.5

Where the value of μ₀/4π = 10⁻⁷

I = 5A

R = 3 cm = 0.03 m

x = point at which magnetic field is to be calculated = 4 cm = 0.04 m

Therefore B = 10⁻⁷* 2π*5* (0.03)² / (0.03²+0.04²)^1.5 î

B = 10⁻⁷* 2π*5* (0.03)² / (0.0009+0.0016)^1.5 î

B = 10⁻⁷* 2π*5* (0.03)² / (25*10⁻⁴)^1.5 î

B = 10⁻⁷* 2π*5* (0.03)² / 125*10⁻⁶ î

B = 36π*10⁻⁷ T î

Therefore magnetic field at point P (4 cm, 0, 0) will be 36π*10⁻⁷ T î.
