Chapter 22: Q26PE (page 812)

Calculate the Hall voltage induced on a patient鈥檚 heart while being scanned by an MRI unit. Approximate the conducting path on the heart wall by a wire 7.50cm long that moves at 10.0 perpendicular to a 1.50鈥�Tmagnetic field.

Short Answer

Expert verified

The induced hall voltage is 1.13脳10鈥�2V.

Step by step solution

01

Given information

The diameter of the aorta is L=7.50cm(1m100cm)=7.50脳10鈥�2mThe magnetic field strength of the earth is B=1.50T

The speed of the aluminum rod is v=10.0cm/s1m/s100cm/s=0.10m/s

02

Concept Introduction

The Hall effect is defined as the generation of a voltage differential (the Hall voltage) across an electrical conductor that is transverse to the current and perpendicular to the applied magnetic field, and this voltage can be estimated using the equation,

E=BLv鈥︹赌︹赌︹赌︹赌︹赌︹赌�(1)

03

Calculation of the Hall Voltage

Substitute the given data in equation (1) will give the value of induced hall voltage such that,

E=1.50T脳7.50脳10鈥�2m脳0.10m\s=1.13脳10鈥�2V

Therefore, the induced hall voltage is 1.13脳10鈥�2V.

(a) Find the charge on a baseball, thrown at\({\rm{35}}{\rm{.0\;m/s}}\)perpendicular to the Earth's\({\rm{5}}{\rm{.00 \times 1}}{{\rm{0}}^{{\rm{ - 5}}}}{\rm{\;T}}\)field, that experiences a 1.00-N magnetic force. (b)What is unreasonable about this result?(c)Which assumption or premise is responsible?

Consider using the torque on a current-carrying coil in a magnetic field to detect relatively small magnetic fields (less than the field of the Earth, for example). Construct a problem in which you calculate the maximum torque on a current-carrying loop in a magnetic field. Among the things to be considered are the size of the coil, the number of loops it has, the current you pass through the coil, and the size of the field you wish to detect. Discuss whether the torque produced is large enough to be effectively measured. Your instructor may also wish for you to consider the effects, if any, of the field produced by the coil on the surroundings that could affect detection of the small field.


(a) A cosmic ray proton moving toward the Earth at 5.00脳107m/sexperiences a magnetic force of 1.70脳10鈥�16N. What is the strength of the magnetic field if there is a 45鈭� angle between it and the proton鈥檚 velocity? (b) Is the value obtained in part (a) consistent with the known strength of the Earth鈥檚 magnetic field on its surface? Discuss.

What radius circular path does an electron travel if it moves at the same speed and in the same magnetic field as the proton in Exercise \({\rm{22}}{\rm{.13}}\)?

Measurements of the weak and fluctuating magnetic fields associated with brain activity are called magnetoencephalograms (MEGs). Do the brain鈥檚 magnetic fields imply coordinated or uncoordinated nerve impulses? Explain.
