Chapter 29: Q. 4 (page 829)

What is the current direction in the wire of FIGURE Q29.4? Explain.

Short Answer

Expert verified

Current is flowing toward out of the paper.

Step by step solution

01

Given information

We have given,

The current carrying wire with shown magnetic field in the diagram.

we have to find the direction of current.

02

Simplify

Using the right hand thumb rule, when we curl over finger along the direction of magnetic field then over thumb will show the direction of current which is out of the paper.

Magnetic resonance imaging needs a magnetic field strength of 1.5 T. The solenoid is 1.8 m long and 75 cm in diameter. It is tightly wound with a single layer of 2.0-mm-diameter superconducting wire. What size current is needed?

What are the strength and direction of the magnetic field at the center of the loop in FIGUREP29.43?

Particle accelerators, such as the Large Hadron Collider, use magnetic fields to steer charged particles around a ring. Consider a proton ring with 36 identical bending magnets connected by straight segments. The protons move along a 1.0-m-long circular arc as they pass through each magnet. What magnetic field strength is needed in each magnet to steer protons around the ring with a speed of 2.5×107m/s ? Assume that the field is uniform inside the magnet, zero outside.

Your employer asks you to build a 20-cm-long solenoid with an interior field of 5.0mT. The specifications call for a single layer of wire, wound with the coils as close together as possible. You have two spools of wire available. Wire with a #18gauge has a diameter of 1.02mmand has a maximum current rating of 6A. Wire with a #26gauge is 0.41mmin diameter and can carry up to 1A. Which wire should you use, and what current will you need?

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?
