16.5 Exercise 30

Avg difficulty 2.5

A radio transmitter broadcasts plane electromagnetic waves whose maximum electric field at a particular location is 1.55×10−3V/m.1.55 \times 10^{−3} \text{V}/\text{m} . What is the maximum magnitude of the oscillating magnetic field at that location? How does it compare with Earth’s magnetic field?
