A straight wire lies along the y-axis. It is initially carrying a current of 10 A in the positive y-direction. This current decreases to zero, then reverses to flow at 10 A in the negative y-direction. In the 1st quadrant a square conducting coil has 2 sides parallel to the y-axis and the other 2 sides parallel to the x-axis. As the current in the straight wire is in the process of changing, in which direction is the induced current...

A long, straight wire carrying a current of I1 =5.0 A perpendicular to the xy plane (page on a table) intersects the x-axis at the origin and points +z direction (out of page). A second, long wire carrying I2 = 12 A intersects the x-axis at x= 6.0 cm and points -z direction (into the page). Find the direction and magnitude of the net magnetic field due to these two currents at (x=0, y= 8.0 cm). First draw a neat...

A long, straight wire of radius a = 2.0 cm is located along the z-axis and carries a current I1 = 2.1 A in the negative 2-direction. A cylindrical conducting shell of inner radius b= 4.0 cm and outer radius c = 5.7 cm coaxial with the wire carries a uniformly distributed current 12 = 7.1 A in the positive z-direction as shown.
