Albuquerque, New Mexico. Magnaflux inspector A.J. Fry at work on an engine wheel axle in the Atchison, Topeka and Santa Fe Railroad shop. The cable in his hand magnetizes the axle as he spreads steel dust over an area. He then cuts the current off and carefully blows the dust away. The steel particles remain, however in any tiny cracks and reveal any surface flaws that might exist. Axles of engine wheels are magnafluxed every 200,000 miles. Sourced from the Library of Congress.
