*I have found all of the answers except for part (d)*

A sliding bar in figure a has a length of 0.531 m and moves at 1.94 m/s in a magnetic field of magnitude 0.240 T. Using the concept of motional emf, find the induced voltage in the moving rod.
V=.247

(b) If the resistance in the circuit is 0.597 O, find the current in the circuit and the power delivered to the resistor. (Note: The current, in this case, goes counterclockwise around the loop.)
A=.414
W=.102

(c) Calculate the magnetic force on the bar.
magnitude N=5.3e-2
direction

(d)Suppose the current suddenly increases to 1.28 A in the same direction as before, due to an increase in speed of the bar.
(a) Find the emf induced in the rod.
enew = V

(b) Find the new speed of the rod.
vnew = m/s

Explanation / Answer

(d) (a) Current (I) passing through the rod = 1.28 A Resistance (R) = 0.597 Induced voltage (V) in the rod is                = IR                   = (1.28 A)(0.597 )                   = 0.76 V (b) New speed (v) of the rod is calculated as                  = BLv              0.76 V = (0.240 T)(0.531 m)(v)                  v = 5.996 m/s                     = 6.0 m/s
