[World's Largest Inductor?]
The enormous elementary
particle detector at the Large Hadron Collider, known as the
Compact Muon Solenoid (CMS), boasts the world's largest
electromagnet: a solenoid 6.0 m in diameter, 12.5 m in length,
carrying 20000 A of electric current, and producing a magnetic
field of 4.0 T at its middle.
(a)
Use this information to estimate the number of coils of wire
in this solenoid. (You can assume that the infinitely long
solenoid approximation applies here.)
(b)
Estimate the
inductance
of this solenoid, approximating the magnetic field inside the
solenoid to be uniform along its entire length.
(c)
How much
time
(in s and min) would it take to build up the full electric current in the
