Figures & Tables

Fig. 1.

The main magnetization, the magnetic hysteresis loop, and the related magnetic characteristics [11]

Fig. 2.

The hysteresis loop changes for steel subjected to cold working or caused by the non-magnetic addition: soft (1) and hardened (2) steels [11]

Fig. 3.

Magnetic measurement system schemes, based on a) permeameter; b) attachable transducer: 1 – the tested object; 2 – magnetizing coil; 3 – yoke of the magnetic circuit; 4 – winding on the tested object for magnetic flux measurement; 5 – magnetic flux density sensor; 6 – movable pole of magnetic circuit.
