Question

If the loop is then converted into a rectangular loop measuring 2.1cm on its shortest side in 6.50ms, and the average emf induced across the loop is 14.7V during this time period, what is A.the strength of the B-field

Answer 1

Answer:

B =34.5T

Explanation:

Given E = 14.7V, L= 2.1cm = 0.021m, t = 6.50ms = 6.50×10-³s

A = L² = 0.021² = 4.41×10-⁴m²

ω = 2π/t = 2π/(6.50×10-³) = 966.64rad/s

E = ωBA

B = E/ωA = 14.7/(966.64×4.41×10-⁴)

B = 34.5T
