Question

The electric field in an electromagnetic wave is moving in a free space given as vec $E =E_ 0 \;sin(⍵t - kz)$ $i$ The corresponding magnetic field will be:

• A. $\frac{E_0}{ c}\; sin(⍵t - kz) \hat j$
• B. $\frac{E_0}{c}\; sin(⍵t - kz) \hat j$
• C. $\frac{E_0}{c}\; cos(⍵t - kz) \hat i$
• D. $\frac{E_0}{c} \;sin(⍵t - kz) \hat i$

Answer 1

Answer: (B)

$\frac{E_0}{c}\; sin(⍵t - kz) \hat j$

Answer 2

The Correct Option is (B): $\frac{E_0}{c}\; sin(⍵t - kz) \hat j$
