Here you see a single loop of stiff wire, 10.0 cm on a side, immersed in a magnetic field of 0.225 T. Suppose that you remove the loop from the field in just 0.00208 sec. What emf or voltage will be induced in the loop? Express your answer to three significant figures and in normal notation.
The space to the right of the y axis in (Figure 1) contains a uniform magnetic field of unknown magnitude that points in the positive z direction. As a conducting square loop placed in the xy plane (oriented with its horizontal and vertical sides parallel to the xx and yy axes) moves to the right across the y axis at a constant speed of 2.0 m/s, a 0.42-V emf is induced in the loop.
If the side length of the loop is 0.30 mm, what is the magnitude of the magnetic field?
B=?
A bar of mass m and resistance R slides without friction in a horizontal plane, moving on parallel rails as shown in Figure P30.49. The rails are separated by a distance d. A battery that maintains a constant emf E is
connected between the rails, and a constant magnetic field B is directed perpendicularly out of the page. Assuming the bar starts from rest attime t = 0, show that at time t it moves with a speed.

- Suppose a conducting rod (mass m, resistance R) rests on two frictionless and resistanceless parallel rails a distance l apart in a uniform magnetic field B (⊥ to the rails and to the rod) as in the figure. At t = 0 the rod is at rest and a source of emf is connected to the points a and b. Find a formula for the net electric field in the moving rod as a function of time for the case, when the source puts out a constant current I.

Wires 1 and 3 are fixed, but wire 2 is free to move. Wire 2 is displaced to the right by a small distance x.

(b) What is the energy per second dissipated in the resistance of the coil?arrow_forwardAn instrument based on induced emf has been used to measure projectile speeds up to 6 km/s. A small magnet is imbedded in the projectile as shown in Figure P23.2. The projectile passes through two coils separated by a distance d. As the projectile passes through each coil, a pulse of emf is induced in the coil. The time interval between pulses can be measured accurately with an oscilloscope, and thus the speed can be determined. (a) Sketch a graph of V versus t for the arrangement shown. Consider a current that flows counterclockwise as viewed from the starting point of the projectile as positive. On your graph, indicate which pulse is from coil 1 and which is from coil 2. (b) If the pulse separation is 2.40 ms and d = 1.50 m, what is the projectile speed?

- The metal rod (shown below) moves to the right on essentially zero-resistance and zerofriction rails at a speed v = 3.0 m/s. The magnetic field B = 0.75T everywhere in the region.a. What is the current through the 5.0-Ω resistor? b. Does the current circulate clockwise or counterclockwise?c. What is the rate at which the resistor produces heat (i.e., the power dissipated bythe resistor)?d. The rod moves 3.0 m/s to the right because an external agent is exerting a constantforce on it to the right. What is the magnitude of this force? e. Use your answer to part (d) to find the rate at which the external agent does workon the rod.f. Discuss the significance of your results for parts (c) and (e).arrow_forwardA 20-cm-circumference loop of wire has a resistance of 0.12 Ω. The loop is placed between the poles of an electromagnet, and a field of 0.55 T is switched on in a time of 15 ms. What is the induced current in the loop?arrow_forwardIn figure below, the magnetig flux through the circular loop of radius r = 1.8 m increases according to the relation ΦB = 5 t2 + 5t + 3, where ΦB is in Webers and t is in seconds. What is the magnitude and direction (clockwise or counterclockwise) of the induced current in the circular loop at t = 1.5 s if the loop has a total resistance of R = 12 Ω? (Choose clockwise direction as the positive and express the direction of the current by using plus or minus signs in the result, which must be in units of Amperes and include 2 digit after the decimal point. That means if you get a result of 9.22 and the direction of the current is clockwise, just type 9.22 or if you find the direction of the current to be counterclockwise, just type -9.22 in the answer box. Maximum of 5% of error is accepted in your answer.)arrow_forward

You have found that it is difficult to create a uniform magnetic field across the entire sliding-bar apparatus shown in 30.8a, with a resistance R connected between the rails. You decide to investigate creating the magnetic field with a long, straight, current- carrying conductor lying next to and parallel to one of the rails, as shown in P30.18. This will create a nonuniform field across the plane of the bar and rails. You set up the apparatus in this way, with the current-carrying wire a distance a from the upper rail. You wish to find an expression for the force necessary to slide the bar at a constant speed of υ to the right in P30.18 if the wire carries a current I. (Hint: Two separate integrations will be required.)arrow_forwardTwo concentric circular coils of wire lie in a plane. The larger coil has 68 turns and a radius of a=8.1 cm. The smaller coil has 99 turns and a radius of b=0.6 cm. The current in the larger coil has a time dependence as shown in the figure. A) Approximately what is the magnitude of the EMF induced in the small coil at t=2 s? Note that on the graph of current versus time, the two ends of the diagonal part of the graph are at (0, 0) and (3, 5). For my answer I keep getting 3.616E-4 V or 1.0849E-4 V both of which are wrong B) Approximately what is the magnitude of the EMF induced in the small coil at t=5 s? For my answer I keep getting 8.068E-5 V or 2.4208E-5 V both of which are wrong.arrow_forward
