Question

At a typical location in the United States, the earth's magnetic field has a magnitude of 5.0×10−5 T and is at a 65∘ angle from the horizontal. You may want to review (Pages 810 - 814) . Part A What is the flux through the 25 cm × 34 cm front cover of your textbook if it is flat on your desk

Answer 1

Flux = 3.85 × 10⁻⁶ T m²

Step-by-step explanation:

A) Magnetic flux = area x magnetic field component perpendicular to the area

Ф = B A cos θ

B = 5 × 10⁻⁵ T

A = area = 0.25 x 0.34 = 0.085 m²

θ = angle = 90 - 65 = 25°

Ф =( 5 × 10⁻⁵)(0.085) cos 25 = 3.85 × 10⁻⁶ T m²
