You are given a certain volume V of copper
from which to make wire with a square cross section.
The wire you make is then used to wind a
one-layer solenoid as shown.
(Ignore the practical necessity for insulation between the wires
and pretend that they can be wound so that the distance between
turns is exactly the width of the wire.)
Your goal is to generate the highest possible magnetic field
at the centre of the solenoid.

For wire of a given cross section and
for a given current I in the wire,
should you make the inside diameter
of the solenoid large or small?
Explain.

- [6 marks]
For a given inside diameter and
for a given voltage
applied to the solenoid,
should you make the wire long and thin
or short and thick? Explain.
