b) The conductor is wrapped around a square stainless steel core (μr = 2410) with square cross-section, outer length is 20 cm and inner length is 16 cm. The field strength of the coil turns out to be the same

as in task a). The current in the coil is measured at 1.482 A. How many

**have the coil.**

__turns__I solved question A but I am stuck at question B.

Any guidance?
