Which type of core material decreases inductance when inserted into a coil?
Pick an answer to check it.
Answer: B. Brass
Brass is a non-magnetic conductor. Eddy currents induced in a brass slug oppose the coil's field, lowering inductance. Ferrite would increase inductance.
Tip: Brass slug lowers inductance.
