Question

In an NMR experiment, the RF source oscillates at 34 MHz and magnetic resonance of the hydrogen atoms in the sample being in- vestigated occurs when the external field Bext has magnitude 0.78 T. Assume that Bint and Bext are in the same direction and take the pro- ton magnetic moment component u, to be 1.41 X 10-26 J/T. What is the magnitude of Bint?

    Answer:

    B_{int}=-0.015T

    Explanation:

    From the question we are told that:

    RF source oscillation speed \sigma= 34 MHz

    The external field Bext =0.78 T.

    Pro- ton magnetic moment component \mu=1.41 X 10-26 J/T

    Generally the equation for magnitude of B_{int} is mathematically given by

    B_{int}=B_{ext}-\frac{h\triangle \sigma}{2 \mu}

    B_{int}=0.78-\frac{6.6*10^{-34}*34*10^6}{2*1.41*10^{26}}

    B_{int}=0.78-0.7957

    B_{int}=-0.015T
