Question
magnetic field (A), then the ring enters the magnetic field that is directed out of the page (B), t slides along uniform magnetic field (C), then leaves the area of the magnetic field (D) and then again slhdes in no Which position will there be an induced current in the ring as it slides along the table? Assume the ma g ield only the outlined area. magnetic field Slls A) A and E only B) B, C and D C) A, C and E only D) B and D only B. E) There is never an induced current Out of page 6) A square conducting wire with N 10 loops has an area of 0.1 m2 and is in a uniform magnetic Sield as 50 ? If the magnetic field changes fromB-0.101 own below A resistor is in the loop and has a resistance of R Br 0.60 T in 0.333 s. What is the induced voltage across the resistor? (Assume normal to area of the coil is along gnetic field lines) X. A)-2.5 V B) - 0.5 V )-5.0 V )-10 VExplanation / Answer
5] option D is correct because flux is changing in these two cases.
6] induced voltage = - rate of change of flux = -NA*dB/dt = -10*0.1*(0.60-0.10)/0.333 = -1.5 V
option c is correct.
