    Given Information:

    Amplitude of the electric field = E = 570 N/C

    Speed of light = c = 3.0x10⁸ m/s

    Required Information:

    Amplitude of the magnetic field = ?

    Answer:

    Amplitude of the magnetic field = 1.90x10⁻⁶ T

    Explanation:

    The relation between the amplitude of the electric field and magnetic field is given by

    B = E/c

    Where c is the speed of light

    B = 570/3.0x10⁸

    B = 1.90x10⁻⁶ T

    Therefore, the amplitude of magnetic field is 1.90x10⁻⁶ T
