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...

An infinite solid cylinder conductor of radius a = 3cm centered
on the z-axis carries a current I1 = 1A. The current is evenly
distributed along the cross section and is directed out of the
screen (positive z-axis direction). An infinite coaxial conductive
surface of radius b = 8 cm carries a current I2 = 4A, towards the
inside of the screen (negative direction z).
What is the magnitude of the magnetic field B inside the inner
cylinder at a...
