Chapter 29: Q. 17 (page 831)

A 100Acurrent circulates around a 2.0mmdiameter superconducting ring.

a. What is the ring鈥檚 magnetic dipole moment?

b. What is the on-axis magnetic field strength 5.0cmfrom the ring?

Short Answer

Expert verified

a. The ring magnetic moment is 3.14脳10-4A.m2.

b. the magnetic field strength is0.5渭罢.

Step by step solution

01

Part (a) Step 1: Given information

We have given,

current = 100A

Diameter = 2mm

We have to find the magnetic dipole moment.

02

Simplify

The magnetic dipole moment of ring is

渭=AI渭=蟺谤2I渭=3.14脳10-6脳100渭=3.14脳10-4A.m2

03

Part (b) Step 1: Given information

We have given,

Distance = 5cm

We have to find the magnetic field strength.

04

Simplify

Magnetic field due to dipole is

B=渭0渭鈫�2蟺搁3B=(4蟺脳10-7)(3.14脳10-4)2蟺(5脳10-2)3B=0.5渭罢

What are the strength and direction of the magnetic field at point P in FIGURE P29.46?

An infinitely wide flat sheet of charge flows out of the page in FIGURE CP29.83. The current per unit width along the sheet (amps per meter) is given by the linear current density Js. a. What is the shape of the magnetic field? To answer this question, you may find it helpful to approximate the current sheet as many parallel, closely spaced current-carrying wires. Give your answer as a picture showing magnetic field vectors. b. Find the magnetic field strength at distance d above or below the current sheet.

A spherically symmetric charge distribution produces the electric field E u = 15000r2 2nr N/C, where r is in m.

a. What is the electric field strength at r = 20 cm?

b. What is the electric flux through a 40-cm-diameter spherical surface that is concentric with the charge distribution?

c. How much charge is inside this 40-cm-diameter spherical surface?

significant figures, what are the cyclotron frequencies in a magnetic field of the ions (a)O2+, (b)N2+and (c)CO+? The atomic masses are shown in the table; the mass of the missing electron is less than 0.001uand is not relevant at this level of precision. Although N7+andCO+both have a nominal molecular mass of 28, they are easily distinguished by virtue of their slightly different cyclotron frequencies. Use the following constants:1u=1.6605脳10鈭�27kg,ee=1.6022脳10鈭�19C.

The element niobium, which is a metal, is a superconductor (i.e., no electrical resistance) at temperatures below 9K. However, the superconductivity is destroyed if the magnetic field at the surface of the metal reaches or exceeds 0.10T. What is the maximum current in a straight,3mm diameter superconducting niobium wire?
