Chapter 22: Q4CQ (page 808)

Noting that the magnetic field lines of a bar magnet resemble the electric field lines of a pair of equal and opposite charges, do you expect the magnetic field to rapidly decrease in strength with distance from the magnet? Is this consistent with your experience with magnets?

Short Answer

Expert verified

Yes, the strength of the force field decreases rapidly with the increase in the distance from the magnet.

Step by step solution

01

Definition of Magnetic field

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.

02

Explanation of solution

The magnetic flux lines are very closely spaced near the magnet, but because thedistance from the magnet increases the gap between the flux lines also increases or we willsay that the flux strength decreases with a rise within the distance from the magnet.

This statement is in step with our experience with a magnet, as the magnet attracts iron objects only up to a particular distance as well as attracts/repels another magnetic within a certain distance.

Discuss the possibility that a Hall voltage would be generated on the moving heart of a patient during MRI imaging. Also discuss the same effect on the wires of a pacemaker. (The fact that patients with pacemakers are not given MRIs is significant.

A 200-turn circular loop of radius50.0cmis vertical, with its axis on an east-west line. A current of 100 A circulates clockwise in the loop when viewed from the east. The Earth's field here is due north, parallel to the ground, with a strength of 3.00×10‐5T. What are the direction and magnitude of the torque on the loop? (b) Does this device have any practical applications as a motor?

A proton moves at\({\rm{7}}{\rm{.50 \times 1}}{{\rm{0}}^{\rm{7}}}{\rm{ m/s}}\)perpendicular to a magnetic field. The field causes the proton to travel in a circular path of radius\({\rm{0}}{\rm{.800 m}}\). What is the field strength?

Volcanic and other such activity at the mid-Atlantic ridge extrudes material to fill the gap between separating tectonic plates associated with continental drift. The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge. What does this imply about the Earth’s magnetic field and how could the knowledge of the spreading rate be used to give its historical record?

A 0.750-m-long section of cable carrying current to a car starter motor makes an angle of 60º with the Earth’s5.50×10-5Tfield. What is the current when the wire experiences a force of localid="1653896077054" 7.00×10‐3N? (b) If you run the wire between the poles of a strong horseshoe magnet, subjecting 5.00 cm of it to a 1.75-T field, what force is exerted on this segment of wire?
