Answer with solution

PROBLEM SOLVING (20PTS) 1. A circular antenna of an area of 3 m is installed at a place in NAIA. The plane of the area of antenna is inclined at 470 with the direction of Earth's magnetic field. If the magnitude of Earth's field at that place is 40773.9 nT find the magnetic flux linked with the antenna, (1 nT = 1x10'T) 2. An emf is induced by rotating a 1000-turn, 20.0 cm diameter coil in the Earth's 5.00x10-5 T magnetic field. What average emf is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0ms?15. A permanent magnet is dropped, south pole-down, through a conducting loop as shown As the magnet falls toward-and then falls past-the area of the loop, what will be the direction of the current flow? bar magnet S clockwise counter clockwise A. Clockwise when falling toward, but counterclockwise as falling away B. Clockwise when falling toward, and clockwise as falling away C. Counterclockwise when falling toward, but clockwise as falling away. D. Counterclockwise when falling toward, and counterclockwise as falling away9-10. How can the magnetic flux through a coil of wire be increased? Select two answers: A. Increase the magnitude of the magnetic field that passes outside the loop. B. Increase the magnitude of the magnetic field that passes through the loop. C. Increase the cross-sectional area of the loop. D. Orient the loop so its normal vector is perpendicular to the external magnetic field direction
