A magnetizing apparatus (1) includes an openable and closeable annular portion (3) formed by a magnet (2). The annular portion (3) includes a lock mechanism (4) configured to hold the annular portion (3) in a closed state. A magnetizing method includes an attaching step of placing an object inside the annular portion (3) by opening and closing the annular portion (3) and attaching the magnetizing apparatus (1) to the object by holding the annular portion (3) in a closed state with the lock mechanism (4), a moving step of moving the magnetizing apparatus (1) relative to the object in the axial direction of the annular portion (3) while the magnetizing apparatus (1) is attached to the object, and a detaching step, after the moving step, of releasing the lock mechanism (4) to detach the magnetizing apparatus (1) from the object.

A non-destructive inspection method of inspecting an inspection target using multiple different types of non-destructive inspection means that include one non-destructive inspection means and at least one other non-destructive inspection means. The method includes determining a marking position on the inspection target in a detection result by the one non-destructive inspection means, causing a device to store the marking position, and fixedly forming a mark on the inspection target corresponding to the marking position. The mark is detectable by the other non-destructive inspection means. The method further includes causing the other non-destructive inspection means to inspect an inspection target including the mark. The method further includes contrasting detection results by the multiple different types of non-destructive inspection means in reference to the mark which is the marking position.

Identification, quantification and characterization of biological micro- and nano-systems is enabled by magnetically spinning these natural, non-magnetic systems with the aid of induced magnetization. Biofriendly magnetic micro- and nano-labels enable magnetorotation in extremely weak electromagnetic fields. The spinning of these micromotors can be observed by a simple, CD-like, optical tracking system. The spinning frequency response enables real-time monitoring of single (cancer) cell morphology, with sub-microscopic resolution, yielding previously undeterminable information. Likewise, it enables super-low detection limits for any (cancer) biomarker.

Systems and methods are provided for implementing and utilizing lighting attachments for use in conjunction with handheld magnetization equipment during non-destructive testing (NDT). The lighting attachments may incorporate snap-fit based designed, and may be configured for providing lighting based on the magnetization function of the magnetization equipment.

Provided is a disclosure for a magnetic particle inspection system configured to generate a magnetic field for inspection of a part, comprising a programmable logic controller (PLC), a current source, and a current sensing device. The PLC may be configured to communicate an amperage signal, for amperage of an output current, to a current source, and communicate a first signal to the current source to output the output current. The current source may be configured to adjust the amperage for the output current based on the amperage signal, and output the output current upon receiving the first signal. The current sensing device may be configured to measure an output amperage of the output current, and communicate amperage information based on the output amperage to a signal conversion device. The PLC may, in response to feedback from the signal conversion device, update the amperage signal.
