31. An explanation in terms of solar cycles in loss of solar magnetic flux was proposed in 2012. 32. H is the applied external magnetic field, M is the total magnetic flux density of the material. 33. This increases the magnetic flux and more power is generated by the traction motors, over short periods. 34. This severe rate of change of magnetic flux induces a high voltage in the coil's secondary windings. 35. A more-sophisticated probe includes a magnetic flux sensor ( Hall effect sensor ) in the magnetic circuit. 36. In conclusion, flux linkage should be interpreted as an extension rather than an equivalent to magnetic flux . 37. This increases the magnetic flux , and more power is generated by the traction motors over short periods. 38. The relationship between EMF and magnetic flux is an equation now known as Faraday's law of induction: 39. If the current is not changing, then the Hall voltage is a measure of the magnetic flux density. 40. These pigs use technologies such as magnetic flux leakage ( MFL ) and ultrasonics to inspect the pipeline.
