[[/Flux fringing|Fringing flux]] can have high magnitude around the [[/air gap]] in a [[/gapped core]]. With a normally [[/laminated core]] two sides expose large surface area of the [[/laminations]] and the fringing flux leaves and enters the core at large angle producing significant [[/planar eddy current|planar eddy currents]] and significant [[/power loss]]. In high-power applications such loss can be so significant that [[/radially laminated core]] must be used.
