Question

Calculate the magnetic flux density when a radius of 35cm, length of 12cm, and current of 16A are given.

A) 0.0003 T
B) 0.0010 T
C) 0.0027 T
D) 0.0038 T

Answer 1

The magnetic flux density can be calculated using the formula B = μ₀I / (2πr), where B is the magnetic flux density, μ₀ is the permeability of free space (constant value), I is the current, and r is the radius. Substituting the given values into the formula, we find that the magnetic flux density is 0.0010 T.

Step-by-step explanation:

To calculate the magnetic flux density, we can use the formula B = μ₀I / (2πr), where B is the magnetic flux density, μ₀ is the permeability of free space (constant value), I is the current, and r is the radius.

Given that the radius is 35 cm, the current is 16 A, and the permeability of free space is a constant, we can substitute these values into the formula:

B = (4π × 10^-7 T m/A) × 16 A / (2π × 0.35 m)

Simplifying the expression, we get:

B = 0.001 T

Therefore, the correct answer is B) 0.0010 T.
