The 12th International Workshop on Electromagnetic Nondestructive Evaluation (ENDE'07) was held from 19th–21st June 2007. The Workshop was hosted by the Wolfson Centre for Magnetics at Cardiff University, Cardiff, Wales, UK with sponsorship from Cedrat SA, Serco Assurance, Rolls-Royce plc, Welsh Assembly Government, Computer Simulation Technology, The Japan Society of Applied Electromagnetics and Mechanics, Engineering and Physical Sciences Research Council. The organizers gratefully acknowledge their support.

The aim of this annual workshop is to bring together engineers and scientists from universities, research institutions and industry to discuss and exchange the latest ideas and findings in basic research and development as well as industrial applications of Electromagnetic Nondestructive Evaluation.

After the introductory welcoming remarks from Dr. David Grant (Vice Chancellor of the Cardiff University), Prof. Hywel Thomas (Head of the School of Engineering, Cardiff University) and Prof. David Jiles (Chairman of the Workshop), the technical program of the Workshop commenced with a plenary talk “NDE Research Makes a Difference” by Prof. Chris Scruby, Director, UK Research Centre in NDE, Imperial College London, U.K. Four distinguished invited speakers discussed the challenges and achievements in various fields of ENDE. Prof. J. Bowler (Iowa State University, USA), gave a talk titled “Integral methods for calculating the interaction of eddy currents with cracks”. Prof. K. Miya (Keio University, Japan), presented the second invited talk on “The Start of a New Field of Electromagnetic and Mechanical Maintenance Engineering”. Prof. G. Dobmann (Fraunhofer-Institute for Non-destructive Testing, Germany), was invited to present “Industrial Applications of 3MA – Micromagnetic Multiparameter Microstructure and Stress Analysis”. Finally Prof. N. Takahashi (Okayama University, Japan) presented an invited talk on “3D Nonlinear Eddy Current Analysis of Electromagnetic Inspection of Defects in Steel”. A total of 75 technical papers were divided into 30 oral and 45 poster presentations. The oral presentations were organized into 7 sessions covering a variety of topics on both theoretical and experimental aspects of NDE in eddy currents, magnetic measurements, magnetic flux leakage, Barkhausen methods, new methods and inverse problems for crack detection. These sessions were chaired by experts in the field including Profs. S. Udpa, L. Udpa, D. Jiles, C. Scruby, P. Nagy, T. Moses, G. Dobmann, K. Miya, S. Takahashi, A. Tamburrino and others. During closing remarks it was announced that the next ENDE Workshop (ENDE2008) will be held June 10–12, 2008 in Seoul, Korea. The ENDE Workshop 2009 will be held in Dayton, Ohio, U.S.A. The conference concluded with remarks from the chairman Prof. David Jiles.

A total of 73 participants from 16 countries were registered for the Workshop. The short versions of the papers were published in the Workshop digest and 39 reviewed full papers were accepted for publication in this proceeding. The organizers would like to thank all the participants for their contribution and all the referees for their role in reviewing the full papers. Lastly, the editors gratefully acknowledge the help and hard work of Ms. Linda Clifford in putting this volume together.
