Question

Enhanced EOC: Problem 25.12 - MC Part A Constants At a typical location in the United States, the earth's magnetic field has a magnitude of 5.5x10-5 T and is at a 70 angle above the horizontal. What is the flux through the 20 cm x31 cm front cover of your textbook if it is flat on your desk?

Explanation / Answer

here,

magnitude of magnetic feild , B = 5.5 * 10^-5 T

theta = 70 degree

area = 0.2 * 0.31 m^2

A)

the flux through the front cover , phi = B * area * sin(theta)

phi = 5.5 * 10^-5 * 0.2 * 0.31 * sin(70) T.m^2

phi = 3.2 * 10^-6 T.m^2
