Abstract
An array of magnets designed of flexible components and materials can be easily shaped to fit to the contour of various curved surfaces and structures. EMATs that incorporate these magnets, in addition to being flexible, may be smaller in volume than the conventional EMAT magnets and therefore easier to apply to complex structures where access may be restricted. Also, flexible multiple-pole magnet arrays can be easily and economically fabricated in various shapes and configurations, thereby increasing versatility, utility and cost effectiveness in comparison to the rigid, conventional magnet designs.
