Ferrite have
Answer: Option
Explanation:
Ferrite is a low density material of composition with Fe2O3 x O, where x is a bivalent metal, such as Cobart, Ni, Mn. These magnetic materials having very low loss of current and used in high frequency circuit.

Yaa, ferrite has high resistance and leads to low eddy current losses. Hence used it in transformers, electromagnetics etc.

A ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed.
It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents).

Ferrites that are used in transformer or electromagnetic cores contain nickel, zinc, and/or manganese compounds. They have a low coercivity and are called soft ferrites. The low coercivity means the material's magnetization can easily reverse direction without dissipating much energy (hysteresis losses), while the material's high resistivity prevents eddy currents in the core, another source of energy loss.
