A copper wire 20.0 m long with radius 4.57 x 103 m and = 1.72 x

Question:

A copper wire 20.0 m long with radius 4.57 x 10–3 m and ρ = 1.72 x 10–8 Ω cm is used to form a solenoid that will produce a magnetic field.

(a) What is the wire’s resistance?

(b) If the wire is connected to a 4.50-V battery, what is the current that passes through the wire?

(d) What will be the length of the solenoid if the coils touch one another?

(e) Find the strength of the solenoid’s magnetic field.
