Axion Dark Matter Detection using an LC Circuit
  It is shown that dark matter axions cause an oscillating electric current to
flow along magnetic field lines. The oscillating current induced in a strong
magnetic field $\vec{B}_0$ produces a small magnetic field $\vec{B}_a$. We
propose to amplify and detect $\vec{B}_a$ using a cooled LC circuit and a very
sensitive magnetometer. This appears to be a suitable approach to searching for
axion dark matter in the $10^{-7}$ to $10^{-9}$ eV mass range.
