An open plastic soda bottle with an opening diameter of 2.5 cm is placed on a table. A uniform 1.75 -T magnetic field directed upward and oriented 25 degree from vertical encompasses the bottle. What is the total magnetic flux through the plastic of the soda bottle?
1 Answer
-
the magnetic flux = B A cos (theta)
= 1.75 x pi r^2 x cos(25)
= 1.75 x 3.14 x (1.25x10^-2)^2 x 0.9063
= 7.78 x10^-4 weber.
