Magnetic field due to currentHard
Question
A plane electromagnetic wave of frequency 40 MHz travels in free space in X-direction. At some point and at some instant, the electric field 
has its maximum value of 750 N/c in Y-direction. The magnitude and direction of magnetic field will be :-
has its maximum value of 750 N/c in Y-direction. The magnitude and direction of magnetic field will be :-Options
A.2.5 μT in X-direction
B.2.5 μT in Y-direction
