Problem 23.29 (Multistep) An accelerated electron An electron is initially at rest. At time t1=0 it is accelerated upward with an acceleration of a= 1 × 1019 m/s2 for a very short time (this large acceleration is possible because the electron has a very small mass). We make observations at location A, x= 16 meters from the electron (see the figure). Part 1 (a) At time t2= 1 ns (1 × 10-9 s), what is the magnitude and direction of...
Problem 22.26 (Multistep) In the figure below a very small circular metal ring of radius r= 0.5 cm and resistance x= 5 Ω is at the center of a large concentric circular metal ring of radius R= 50 cm. The two rings lie in the same plane. At t= 3 s, the large ring carries a clockwise current of 5 A. At t= 3.3 s, the large ring carries a counterclockwise current of 8 A. Part 1 (a) What is...
An infinite straight wire carries current I1 = 3 A in the positive y-direction as shown. At time t = 0, a conducting wire, aligned with the y-direction is located a distance d = 41 cm from the y-axis and moves with velocity v = 18 cm/s in the negaitve x-direction as shown. The wire has length W = 28 cm. 1)What is ε(0), the emf induced in the moving wire at t = 0? Define the emf to be...
A current-carrying wire moves toward a coil A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns, which is attached to a voltmeter as shown. The long wire is in the plane of the coil. (Only a small portion of the wire is shown in the diagram.) Voltmeter N turns radius r The radius of the coil is 0.02 m, and the coil has 11 turns. At...
2 parts, thx:) 1) Current of 4.0 A flows in the coil as shown in the figure. The coil has 4 loops and is situated in the xz-plane. The area of the coil is 3.00 x 10-3 m2. The coil is situated in a uniform magnetic field = (2.00- 5.00- 5.00mT. What is the magnitude of the torque acting on the loop due to the magnetic field? Give your answer in µNm (micro-Newton meters). 2) Current of 2.0 A flows...

In the image below, a 5.0A current travels through an otherwise straight wire that loops in a 2cm-diameter circle. What is the magnitude and direction of the magnetic field in the center of the loop due only to the linear portion of the wire? What is the magnitude and direction of the magnetic field in the center of the loop due only to the circular portion of the wire? What it the net magnetic field (both magnitude and direction) in...
