| 31. | A similar effect is the proximity effect, which is caused by externally induced eddy currents.
|
| 32. | Although the hysteresis loss is less than the eddy current loss, it is not negligible.
|
| 33. | Magnets are already used in eddy current brakes on trains, roller coasters and power tools.
|
| 34. | These core losses come from the change in the direction of the flux and eddy currents.
|
| 35. | Tubing inspection is generally limited to non-ferromagnetic tubing and is known as conventional eddy current testing.
|
| 36. | The two coils are wound in opposite directions to each other, cancelling out the eddy currents.
|
| 37. | Eddy current losses are caused by currents induced in the iron due to the alternating flux.
|
| 38. | The braking system is a passive eddy current braking which is designed to have deceleration capabilities.
|
| 39. | From this, it can be seen that the thinner the laminations, the lower the eddy current losses.
|
| 40. | An eddy current brake was not fitted.
