# How to find the Magnetic Field by using Maxwell’s Equation

Welcome to www.apniphysics.com . In this video I have solve a problem related to the Electrodynamics, if electric field component is given and the direction of propagation of EM -wave is known then how to find the magnetic field component using the differential form of the Faraday’s Law. Step1. First solve the LHS by using the proper form of the Curl E that is equivalent to the determinant, by putting the components properly expand it component wise. After finding the resultant of this determinant that comes only with one unit vector (i,j or k). put this value and equate with the RHS according to components of i,j and k. after comparing the component solve it LHS and then integrate.
