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 1

`B_(int)=-0.015T`

Step-by-step 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)-(h\triangle \sigma)/(2 \mu)`

`B_(int)=0.78-(6.6*10^(-34)*34*10^6)/(2*1.41*10^(26))`

`B_(int)=0.78-0.7957`

`B_(int)=-0.015T`
