The value of the electric and magnetic fields in a particular reference frame in some units varies with time which is given by:
\(\vec{E}= 3 t \hat{x} + 4 t^2 \hat{y} + 7 \hat{k} \), \(\vec{B}= 5 t \hat{x} + 7 \hat{y} + 8 \hat{k} \).
There is a particle moving with some relativistic velocities observes the electric field to be of the form:
\(\vec{E}= 5 t^2 \hat{k} \).
How the magnetic field in z direction will behave at some late time?
