Question

Quizplus · Accepted Answer

The maximum magnetic field (B) can be found using the equation:
B = E/c, where c is the speed of light in vacuum (given as 3.0 × 10^8 m/s).
In this case, E = 1200 V/m. 
Plugging in the values, 
B = 1200/3.0 × 10^8 = 4.0 × 10^-6 T
Therefore, the best choice is B, which is 4.0 × 10^-6 T.
