30. Induction and Inductance
Magnetic Flux
4PRACTICE PROBLEM
The axis of a circular coil is rotated from 30° to 70° in 0.050 s with respect to the earth's magnetic field. The coil's cross-section area is 16 cm2 and the number of turns in the coil is 300. Earth's magnetic field has a value of 7.0 × 10-5 T. Calculate the total magnetic flux through the coil initially and finally.
