We present a micron-sized induction magnetometer designed to measure the magnetic response of superconducting mesoscopic samples. The device is manufactured using the Memscap PolyMUMPs process and consists of two octagonal planar parallel micro-coils covering an area of 240 microns X 240 microns, which are separated by only 2.75 microns. We show that this design is sufficiently sensitive to detect the Meissner transition at zero dc field, of a high-Tc superconductor Bi2Sr2CaCu2O8 disk of 40 microns in diameter and 1 micron in thicknesses.
