涡流损耗导体在非均匀磁场中移动或处在随时间变化的磁场中时，因涡流而导致的能量损耗。涡流是上述情况下导体内的感生的电流。这种电流在导体中形成一圈圈闭合的电流线，称为涡流（又称傅科电流）。涡流损耗的大小与磁场的变化方式、导体的运动、导体的几何形状、导体的磁导率和电导率等因素有关。涡流损耗的计算需根据导体中的电磁场的方程式，结合具体问题的上述诸因素进行。置于随时间变化的磁场中的导体内，也会产生涡流，如变压器的铁心，其中有随时间变化的磁通，它在副边产生感应电动势，同时也在铁心中产生感应电动势，从而产生涡流。这些涡流使铁心发热，消耗电能，这是不希望有的。但在感应加热装置中，利用涡流可对金属工件进行热处理。大块的导体在磁场中运动或处在变化的磁场中，都要产生感应电动势,形成涡流,引起较大的涡流损耗。为减少涡流损耗，常将铁心用许多铁磁导体薄片（例如硅钢片）叠成，这些薄片表面涂有薄层绝缘漆或绝缘的氧化物。磁通穿过薄片的狭窄截面时，涡流被限制在沿各片中的一些狭小回路流过，这些回路中的净电动势较小，回路的长度较大，再由于这种薄片材料的电阻率大，这样就可以显著地减小涡流损耗。所以，交流电机、电器中广泛采用叠片铁心。
