Question

Please solve and explain how its done.

A thin (radius r=0.6 mm) long wire is used to build a solenoid: the wire is densely (subsequent turns touching each other) wound around a cylindrical surface of the diameter D=2.3 cm. When electric current 1=4.3 A runs in this wire, what is the magnitude Bsol of the magnetic field in the center of the solenoid?: Bsol= G. Let us now compare that magnetic field to the magnetic field B1 that would be produced just by a single circular loop of this wire at circle's center with the same diameter D and running the same current I): B1/Bsol=
