Calculate the magnetic field due to an electric field E = (75i – 45j) x 10^8 V/m.
Question
Calculate the magnetic field due to an electric field E = (75i – 45j) x 10^8 V/m.
Solution
The magnetic field cannot be directly calculated from the electric field. They are two different entities. However, they are related in the context of electromagnetic waves. In an electromagnetic wave, the electric field (E) and the magnetic field (B) are perpendicular to each other and the direction of propagation of the wave.
The relationship between the magnitudes of E and B in free space is given by the equation:
B = E / c
where c is the speed of light in vacuum, approximately 3 x 10^8 m/s.
However, to calculate B from E, we need to know that the fields form an electromagnetic wave and the direction of propagation. The given information is not sufficient to calculate B.
