Chapter 29: Q. 5 (page 829)

What is the current direction in the wire of FIGURE Q29.5? Explain.

Short Answer

Expert verified

The current direction will be downward.

Step by step solution

01

Given information

We have given,

a current carrying wire producing the magnetic field around it.

We have to find the direction of current in wire.

02

Simplify

From the diagram, here the cross sign indicates the magnetic field inward the paper and the dot sign indicts the magnetic field outward the paper.

Now by using right hand thumb rule curl the field in the direction of magnetic field and the thumb will show the direction of current which is downward.

You have a 1.0-m-long copper wire. You want to make an N-turn current loop that generates a 1.0 mT magnetic field at the center when the current is 1.0 A. You must use the entire wire. What will be the diameter of your coil?

A proton moves along the x-axiswith vx=1.0脳107m/s. As it passes the origin, what are the strength and direction of the magnetic field at the (x,y,z)positions (a) (1 cm, 0 cm, 0 cm) (b) (0 cm, 1 cm, 0 cm) (c) (0 cm, -2 cm, 0 cm)

The Hall voltage across a conductor in a55mTmagnetic field is1.9渭V. When used with the same current in a different magnetic field, the voltage across the conductor is2.8渭V. What is the strength of the second field?

Radio astronomers detect electromagnetic radiation at 45 MHz from an interstellar gas cloud. They suspect this radiation is emitted by electrons spiraling in a magnetic field. What is the magnetic field strength inside the gas cloud?

The coaxial cable shown in figureP29.56consists of a solid inner conductor of radius R1surrounded by a hollow, very thin outer conductor of radius R2. The two carry equal currents I, but in opposite directions. The current density is uniformly distributed over each conductor.

a. Find expressions for three magnetic fields: within the inner conductor, in the space between the conductors, and outside the outer conductor.
