Question: The pole pieces of one magnet are 45 cm x 45 cm in cross section. The magnetic field between them is uniform and of strength 0.8 T.
Part a: Calculate the flux through an area (45 cm x 45 cm) normal to the field direction.
Part b: Show the magnetic field lines as they move from the area A. Is there an angle is you have a perpendicular field, and demonstrate how this angle affects your flux.
Explain each and every step in detail.
