A certain superconducting magnet in the form of a solenoid of length 0.60 m can generate a magnetic field of 6.0 T in its core when its coils carry a current of 120 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find the number of turns in the solenoid.

Expert Solution

The formula for the magnetic field in a solenoid is

B = μ_oNI/l

N = Bl/μ_oI

N = (6)(.6)/(4π X 10^-7)(120)

N = 23873 turns

1. The length of snakes can vary between 0.8m and 2.3 m long. In a large population of snakes there were just 2 of 2.3m length out of 560 snakes. How many genes are involved in determining this character? 2. A) The heights of two true-breeding strains of maize were both 1.75m and when crossed the F1 height was also 1.75m. Selfing the F1 produced an F2 with a range of heights from 1.59 to 1.91m. Out of the F2...

A uniform thin rod of length 0.4 m and mass 0.5 kg can rotate in a horizontal plane about a vertical axis on the left end of the rod. The rod is at rest when a 10.0-g bullet traveling in the horizontal plane of the rod is fired into the right end of the rod at an angle 90o with the rod. The bullet lodges in the rod and the angular velocity of the rod is 10 rad/s immediately after...

The thin uniform rod in the figure has length 5.0 m and can pivot about a horizontal, frictionless pin through one end. It is released from rest at angle θ = 50° above the horizontal. Use the principle of conservation of energy to determine the angular speed of the rod as it passes through the horizontal position. Assume free-fall acceleration to be equal to 9.83 m/s2.
