A 62.0 m length of insulated copper wire is wound to form a solenoid of radius 1

Question

A 62.0 m length of insulated copper wire is wound to form a solenoid of radius 1.8 cm. The copper wire has a radius of 0.48 mm.
(a) What is the resistance of the wire?
O

(b) Treating each turn of the solenoid as a circle, how many turns can be made with the wire?
turns

(c) How long is the resulting solenoid?
m

(d) What is the self-inductance of the solenoid?
mH

(e) If the solenoid is attached to a battery with an emf of 6.0 V and internal resistance of 350 mO, compute the time constant of the circuit.
ms

(f) What is the maximum current attained?
A

(g) How long would it take to reach 99.9% of its maximum current?
ms

(h) What maximum energy is stored in the inductor?
mJ

Explanation / Answer

(a) 5.76 ohms (b) 548.2 turns There is not enough information to get anything past b. You should have something like magnetic flux or field and perhaps a known value for a current.
