Question

The major problem encountered with the sinusoidal type of magnetic field is that the blood vessel and the fluid contained in it act as the primary coil of a transformer when the probe magnet is excited.

(a) True

(b) False

This question was addressed to me at a job interview.

Origin of the question is Cyber Medicine in division Telemedicine Technology of Biomedical Instrumentation

Answer 1

The correct choice is (b) False

Easy explanation: False, the major problem encountered with the sinusoidal type of magnetic field is that the blood vessel and the fluid contained in it act as the secondary coil of a transformer when the probe magnet is excited. As a result, in addition to the induced flow voltage, there is an induced artefact voltage generally referred to as ‘transformer voltage’.
