A thin (radius r=1.15 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=7.8 cm.
When electric current I=1.5 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=
______.
