Question

1.What is the max electric field strength in an electromagnetic wave that has a maximum magnetic field strength of 5 x 10^-4 T (about 10mtimes the Earth's)?

Answer 1

Solution

The given data in question

Maximum magnetic field strength

$B_{max}=5 \times10^{-4} T$

Now

Maximum electric field strength

$E_{max}=B_{max}c$

Where c is speed of light

Putting all values

$E_{max}= 5 \times10^{-4}\times 3\times10^8\\=15\times10^4V/m$
