Answer:
14.4 x 10⁻⁶ Wb
Explanation:
N = Number of turns in the coil = 200
A = Area enclosed by the coil = 12 cm² = 12 x 10⁻⁴ m²
B = Earth's magnetic field at the lab location = 6 x 10⁻⁵ T
Φ = total magnetic flux through the coil
Total magnetic flux through the coil before it is rotated is given as
Φ = N B A
Inserting the values
Φ = (200) (6 x 10⁻⁵) (12 x 10⁻⁴)
Φ = (1200 x 10⁻⁵) (12 x 10⁻⁴)
Φ = 14.4 x 10⁻⁶ Wb
