Barkhausen effect

The phenomenon of discontinuous changes in the magnetization of a magnetic material while the magnetizing field is smoothly varied. It is the consequence of sudden changes in the domain structure as domain walls overcome various pinning defects and to a lesser extent as domain orientations discontinuously rotate away from preferred crystal areas H. G. Barkhausen (in 1919) detected voltage pulses induced in coils surrounding a magnetic sample as it was magnetized. Analogous ultrasonic emissions are also associated with the magnetization of magnetostrictive materials. The character of Barkhausen emissions is strongly dependent on microstructure and stress.

People who carpool often receive discounts because they drive less frequently.

2. Your Driving History

Being a good driver matters to car insurers. Many insurance companies offer special discounts to good drivers. If you have had a series of accidents or traffic violations, you may pay more for your premium. If you have not carried car insurance in several years, you may also pay more for your policy.
