1.) A rectangular copper strip 1.5 cm wide, 0.1 cm thick carries a current of 5 A. A 1.2 T magnetic field is applied perpendicularly to the strip. Find the Hall voltage that should be produced
2.) Two long parallel wires a distance d apart, carry equal currents I in the same direction. One wire is at x = 0, the other at x = d. Determine B between the wires as a function of x
