Answer:
Explanation:
area of loop = 6.3 x 10⁻⁴ m²
Total flux ( initial )
nB A
= 150 x .06 x 6.3 x 10⁻⁴
Final magnetic flux
150 x .03 x 6.3 x 10⁻⁴
change in flux
150 x .06 x 6.3 x 10⁻⁴ - 150 x .03 x 6.3 x 10⁻⁴
= 28.35 x 10⁻⁴ Weber .
b ) voltage induced = rate of change of flux
= change in flux / time
= 28.35 x 10⁻⁴ / 15 x 10⁻³
= 1.89 x 10⁻¹ V
c )
current induced = voltage induced / resistance
= 1.89 x 10⁻¹ / 4
= .4725 x 10⁻¹ A
= 47.25 m A .
