Question

The transducer used for magnetic flux density measurement is

• A. LVDT
• B. Synchro
• C. Hall effect transducer
• D. Thermocouple

Answer 1

The correct option is C Hall effect transducer

$\text{For Hall effect transducer}$

$\text{e}=\frac{k_{H}IB}{t}$

$\text{e}=\text{emf}$

$\text{B}=\text{flux density}$

$\text{e}\propto \text{B}$

i.e., Hall effect transducer useful for measurement of the flux density.
