Steel sheets
Aluminium
Ferrite
Copper
Answer is Right!
Answer is Wrong!
The correct answer is D. Copper.
LVDT windings are wound on copper because it is a good conductor of electricity. This allows the LVDT to accurately measure small changes in magnetic field.
Steel sheets are not a good conductor of electricity, so they would not be suitable for winding LVDT windings.
Aluminium is a good conductor of electricity, but it is not as good as copper. This means that LVDT windings made from aluminium would not be as accurate as those made from copper.
Ferrite is a type of ceramic material. It is not a conductor of electricity, so it would not be suitable for winding LVDT windings.
