In Figure 3 a circular loop of wire of radius R is initially located in the plane of the page while a uniform Magnetic field of magnitude 5 T is coming out the page in the 2 = (0,0,1) direction (represented by the "x"'s). At time t = 0 the loop begins to rotate in uniform circular motion such that the top begins moving out of the page and the bottom moves into the page with a frequency of 5 seconds (i.e. the loop has the same orientation as that at t=0).

A rectangular wire loop of height h, width w, and net electrical resistance R lies in the x-y plane. As shown in the figure below, the entire region x < 0 of space is occupied by a constant, uniform magnetic field which points in the –z direction (into the page). In order to determine the magnitude of this field, a student pulls the wire loop out of the magnetic field region at a constant velocity v in the +x-direction, and measures the current I induced in the loop during this process.

A bar magnet is attached solidly to a frictionless surface and its length is aligned with the x axis. To the right of the first magnet a short distance away is a second bar magnet with its center placed on the x axis and its length perpendicular to the x axis. The second magnet is free to move. Once placed in position at rest, which best describes the initial motion of the second magnet? O The magnet will move away from the fixed magnet. The magnet will not move. The magnet will start to rotate. O The magnet will move toward the fixed magnet.

Two parallel long (infinite for our purposes) wires are oriented along the z-axis. The figure below shows the (xy)-plane perpendicular to the wires, including the positions where the wires cross this plane. The wires carry some unknown electric currents I₁ and I₂, which you need to find from a single measurement of the magnetic field B=B₂ i + By J at point A, whose position in the plane is also indicated. We will treat the currents algebraically: the current I is positive when it runs in the direction of the z-axis and negative when it runs in the opposite direction. In the right-hand system of coordinates, the z-axis is directed out of the screen towards us. The geometric parameters are known: a=0.52 cm, b=0.34 cm. 1₁ a a 1₂ Given the measurement of the magnetic field: By=-0.52 G and By=-0.48 G, what is the unknown current I₁?: 4₁= What is the unknown current I₂?:
