In the gurer a metal rod is forced to move with constant velocity along two parallel metal rails, connected with a strip of metal at one end.A magneticeld of magnitude B = 0.489T points out ofthe page. (a) Ifthe rails are separated by 25.1 cm and thespeed of the rod is 51.6 cmfsrwhat is the magnitude ofthe emfgenerated in volts? [bl Ifthe rod has a resistance of 22.0I O and the rails and connector have negligible resistance, what is the current in amperes in the rod? [cl At what rate is energy being transferred to thermal energy? (a) Number Units v. lb) Number Units v (cl Number Units V A coil C of N = 117turns is placed around a longsolenoid S of radius R = 5.03 cm and n = 225 turns per meter, as in thegure below. {a} What is the mutual inductanceforthe coilsolenoid combination? [b1 Does it depend on theshape,size, or possible lack of close packing ofthe coil? {a} Number n _ Units _ V lb) ~93 A coil is connected in series with a 13.8 k0 resistor. An ideal 46.0V battery is applied across the two devices, and the current reaches a value of 2.47 mA after 6.87 ms. {a} Find the inductance of the coil. lb) HOW much energy is stored in the coil atthis same moment? [a] Number a Units v [bi Number n Units V
