1) since inside cunductor magnetic field is zero
there fore 
and magnetic field outside conductor = 
Where d is distance from conductor
there fore
2)

A conducting rod is being dragged along conducting rails, as shown in (Figure 1)
Part A A conducting rod is being dragged along conducting rails, as shown in (Figure 1). The magnetic field is directed out of the screen. In what direction does the induced current flow through the light bulb? There is no induced current. The induced current flows through the bulb from the left to the right. The induced current flows through the bulb from the right to the left. Part B A circular loop of conducting wire is moving through a uniform magnetic field, as...

PROBLEM 2 - 10 points A square loop travels at a constant velocity of 10 cm/s to the right through a region of magnetic field. The magnetic field is confined to the outlined rectangular region outlined. The magnetic field is directed into the page in the left half of this region, and out of the page in the right half. The small squares on the diagram measure 10 cm x 10 cm, and the loop is shown at time t=0....

1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...

Section 3 Bout A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is JO550 m, and the magnetic field initially has magnitude KO.410 T (a) Suppose that, over a time period of L..o0s, the...
