Final answer:
To calculate the magnetic flux density at a distance of 10 cm from the north pole, use the formula B = μ₀I/2πr. Given the magnetic strength of 10000 A.M and the distance of 10 cm, the magnetic flux density is approximately 0.0251 T.
Step-by-step explanation:
To calculate the magnetic flux density at a distance of 10 cm from the north pole, we can use the formula B = μ₀I/2πr, where B is the magnetic flux density, μ₀ is the permeability of free space (4π x 10⁻⁷ T·m/A), I is the magnetic strength (current) in amperes, and r is the distance from the charge in meters.
Given that the magnetic strength is 10000 A.M and the distance is 0.10 m, we can substitute these values into the formula to find the magnetic flux density:
B = (4π × 10⁻⁷ T·m/A)(10000 A.M)/(2π × 0.10 m)
Simplifying the equation, we get:
B ≈ 0.0251 T
Therefore, the correct answer is not listed. The magnetic flux density of the charge at a distance of 10 cm in air from the north pole with a magnetic strength of 10000 A.M. is approximately 0.0251 T.
