A copper rod of length 0.97 m is lying on a frictionless table (see the drawing). Each end of the rod is attached to a fixed wire by anunstretched spring that has a spring constant of k =78 N/m. A magnetic field with a strength of 0.27 T is oriented perpendicular to thesurface of the table. (a) What must be the direction of the current in the copper rod that causes the springs to stretch? (b) If the currentis 14 A, by how much does each spring stretch?Table(top view)Fixed wires(out of paper)-Copper rod

Solution: a). In order to stretch the spring, a magnetic force is required which pulls the copper…

Answered: unstretched spring that has a spring…

Suspended Rectangular Wire Loop The diagram below depicts a rectangular wire loop of width a = 14.5 cm and height b = 7.35 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.25 A in the wire. The loop is suspended in a uniform magnetic field B = 0.85 T that points in a vertical direction as shown in the diagram, and it would hang vertically if there were no current in the wire. We assume that the wire is massless, but tw masses m = 8.85 g are suspended at the lower corners. B Pivot m m 8 What is the angle, e, at which the loop is in equilibrium?
