Fabrication and characterization of nano electro-magnets are reported. The nano-transformer consisting of two concentric loops has been made and Faraday's induction experiment has been successfully performed. The mutual inductance value extracted from the measured induced current is consistent with the simulated results of mutual inductance between two macroscopic loops with nano-meter spacing. It is also demonstrated that only a small number of magnetic particles can be captured by controlling the design and current level of the electro-magnet.
