← A metal bar 0.72 m long slides at 3.9 m/s across a uniform field of 0.047 T. The bar, its velocity and the field are at right angles to one another. What is the emf between the ends of the bar?A closed circuit includes a coil of 65 turns, and its total resistance is 17 Ω. During 0.42 s the flux through each turn rises by 3.1 mWb. What total charge passes a point of the circuit? →
