Short Answer

Which of the particles in Figure 12.47 has the greatest velocity, assuming they have identical charges and masses?

From the diagram, the 'a' particle has a greater radius and a quicker velocity than the 'b' particle.

Step by Step Solution

TABLE OF CONTENTS

Step 1: Definition of charged particle

A charged particle is a particle with an electric charge in physics. It could be an ion, such as a molecule or atom having an excess or shortage of electrons in comparison to protons. It might also be an electron, proton, or other elementary particle, all of which are thought to have the same charge.

Step 2: Finding the signs of the charges on the particles

The magnetic force can provide centripetal force, causing a charged particle to move in a circular path with a radius of \(R\).

\(\begin{array}{l}{\rm{R = }}\frac{{{\rm{mv}}}}{{{\rm{qB}}}}\\{\rm{R}} \propto {\rm{v}}\end{array}\)

That is, charge and mass are identical at the same magnetic field.

Therefore, the 'a' particle has a larger radius and a faster velocity than the 'b' particle, as seen in the diagram.

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.

If one of the loops in Figure 22.49 is tilted slightly relative to the other and their currents are in the same direction, what are the directions of the torques they exert on each other? Does this imply that the poles of the bar magnet-like fields they create will line up with each other if the loops are allowed to rotate?

How far from the starter cable of a car, carrying 150 A, must you be to experience a field less than the Earth’s 5.00×10-5T ? Assume a long straight wire carries the current. (In practice, the body of your car shields the dashboard compass.)

Figure 22.57shows a long straight wire near a rectangular current loop. What is the direction and magnitude of the total force on the loop?

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?
