1.) We consider a thin metal strip with conductivity o and thickness d oriented in the (x,y)-plane and moving at constant velocity v = vj in the y-direction, as shown. The metal strip falls in the air gap between the rectangular pieces of an electromagnet. The cross-sectional with of each pole is w along the r-direction) and length 1 (along the vertical). The electromagnet produces the magnetic field B = Bk (out-of-the-page). We treat this problem approximately by considering the...

(a) A uniform disk of mass 14 kg, thickness 0.5 m, and radius 0.4 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the +y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.5 s. What is the rotational angular momentum of the disk? What is the rotational kinetic...
