ABSTRACT:
An inductor for an electromagnetic mold used for example for continuous casting of long format rolling ingots has a metallic loop with a hollow space in it to convey a coolant. The vertical dimension at the middle of the sidewall (H.sub.1) of the loop is a multiple of the vertical dimension (H.sub.2) at the corners of the loop. Such a device compensates for the shrinkage which occurs at the sidewall of the ingot and yields ingots which do not suffer from the concavity which would otherwise occur there.
