Question:
A loop antenna, such as is used on older televisions to pick up UHF broadcasts, is 25 cm in diameter. The plane of the loop is perpendicular to the oscillating magnetic field of a 150 MHz electromagnetic wave. The magnetic field through the loop is B = (20 nT)sin ωt.
a. What is the maximum emf induced in the antenna?
b. What is the maximum emf if the loop is turned 90 to be perpendicular to the oscillating electric field?
