answer choices in the second screenshot A lab group has been tasked with conducting an experiment to see if the electric currentflowing through a wire has any effect on a magnetic compass. The group sets up a straightlength of wire on the surface of their lab bench and then connects the two ends to abattery to get current to flow through the wire. Next, the group sets the compass flat onthe table at three different points, as seen in the diagram below:Point APoint BPoint CWireBatteryTABLE (top view)The needle of the compass was unaffected at every point. The lab group concludes thatthe electric current flowing through a wire has no effect on a magnetic compass. Are theresults of their experiment enough to validate this claim? No, because they didn't test the location of the compass at every point around thewireYes, because they used the compass to test the effect in several different locationsalong the wireNo, because they didn't try the experiment with multiple compassesYes, because they only changed one variable at a time

The experimental result depends on the sensitivity of the compass

A very long, cylindrical wire of radius a has a circular hole of radius b in it at a distance d from the center. The wire carries a uniform current of magnitude I through it.

Find the magnetic field (a) at a point at the edge of the hole closest to the center of the thick wire, (b) at an arbitrary point inside the hole, and (c) at an arbitrary point outside the wire. (Hint: Think of the hole as a sum of two wires carrying current in the opposite directions.)
A wire carries current in the plane of this paper toward the top of the page. The wire experiences a magnetic force toward the right edge of the page.

A charged particle is moving perpendicular to a magnetic field in a circle with a radius r. (i) An identical particle enters the field, with v perpendicular to B, but with a higher speed than the first particle. Compared with the radius of the circle for the first particle, is the radius of the circular path for the second particle (a) smaller, (b) larger, or (c) equal in size? (ii) The magnitude of the magnetic field is increased. From the same choices, compare the radius of the new circular path of the first particle with the radius of its initial path.

What creates a magnetic field? More than one answer may be correct. (a) a stationary object with electric charge (b) a moving object with electric charge (c) a stationary conductor carrying electric current (d) a difference in electric potential (e) a charged capacitor disconnected from a battery and at rest. Note: In Chapter 24, we will see that a changing electric field also creates a magnetic field.
The right-hand rule is a way to determine the direction of the magnetic field produced by moving charges. Imagine wrapping your right hand around the path of the charges so that the positive charges (or the current) flow from the little finger side of your fist to the thumb side (Figure 8.53). Then your fingers circle the path in the same direction as the magnetic field lines. Use this rule to verify the directions of the magnetic fields shown in Figures 8.8 and 8.10. How would you use the rule to find the direction of the magnetic field lines around a moving negative charge?
A proton enters a region with a uniform electric field E=5.0kV/m and a uniform magnetic field B=5.0104kT. The proton has initial velocity v0=2.5105m/s. How far along the z axis does the proton travel after it undergoes three complete revolutions?

A particle’s path is bent when it passes through a region of non-zero magnetic field although its speed remains unchanged. This is very useful for “beam steering’’ in particle accelerators. Consider a proton of speed 4106m/s entering a region of uniform magnetic field 0.2 T over a 5-cm-wide region. Magnetic field is perpendicular to the velocity of the particle. By how much angle will the path of the proton be bent? (Hint: the particle comes out tangent to a circle.

(b) Calculate the number of times per second that an electron circles around a magnetic field line.
