Calculate the Larmor frequency:
Problem:
Calculate the Larmor frequency for a proton kept in an external magnetic field of 7.1 T.
Answer:
The Larmor precessional frequency, ν = gN µNB0/h
Substituting the values of different parameters we get,
ν = 5.585 × 5.05 × 10 -27 J T-1 × 7.1 T / 6.626 × 10-34 J s
= 3.02 × 108 s -1
= 302 × 106 Hz = 302 MHz
