Question

The Angular frequency of precession is given by W=2pv=rBo, where v is _____________

(a) ratio of magnetic moment to angular momentum

(b) density of steady magnetic field

(c) frequency of radiation

(d) length of coil

I have been asked this question in examination.

Query is from Cyber Medicine topic in chapter Telemedicine Technology of Biomedical Instrumentation

Answer 1

The correct answer is (c) frequency of radiation

For explanation I would say: The angular frequency (Larmor frequency) of this precession is given by:

W = 2p v = r Bo

Where r is the ratio of the magnetic moment to the angular momentum (the magnetic gyro ratio) and Bo is the density of the steady magnetic field and v is the frequency of radiation.
