To construct a solenoid, you wrap insulated wire uniformly around a plastic tube 14 cm in diameter and 60 cm in length. You would like a 2.2 A current to produce a 2.5 kG magnetic field inside your solenoid.

What is the total length of wire you will need to meet these specifications?

L = km

23.9Km

Explanation:

The following data are given

diameter, d =14cm =0.14m

r=d/2=0.07m

length,l=60cm

current,i=2.2A

magnetic field of 2.5kG we convert to telsa

First we determine the total number of turns from

Sine it is circular, the length of the wire is

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
