Question

Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. They are used to ignite nuclear fusion, for example. Such a laser may produce an electromagnetic wave with a maximum electric field strength of 2.5 x 1011 V/m for a time of 1.00 ns. What is the maximum magnetic field strength in the wave?

    Answer:

    The maximum magnetic field strength is 833.33 T

    Explanation:

    The maximum magnetic field strength is equal:

    B=\frac{E}{c}

    Where

    E = electric field strength = 2.5×10¹¹V/m

    c = speed of the light = 3×10⁸m/s

    Replacing:

    B=\frac{2.5x10^{11} }{3x10^{8} } =833.33T
