PHY 2054, Physics II, M table top where there is no the ring eners the magnetic field that is directed out of the. will there be an induced current in the ring as it slides along the ta slides along at a constant velocity on a frictionless is directed out of the page (B), it slides eld (D) and then again slides in no magnetic field along in the A conducting metal ring uniform magnetic field (), then leaves the area of the magr Which position will there be an induced current in only the outlined area. table? Assume the magnetic field fills velocity of rin A) A and E only B) B, C and D C) A, C and E only D) B and D only E) There is never an induced current Out of page with N = 10 loops has an area of 0.1 m2 and is in a uniform magnetic field as A squa e conduct gw op anc has a resistance ofR-50? 24 shown below. A resistor is in the loop and has a resistance of R = 50 ? . Ifthema to B-0.60 T in 0.333 s. What is the induced voltage across the resistor? Ifthe magnetic field changes from B: 0.10 T (Assume normal to area of the coil is along magnetic field lines) A) 2.5 V B) -10 V C) -0.5 V D) -5.0 V E) 1.5 V X R XExplanation / Answer
5) (D) B and D only
Emf is induced only when the flux linked (i.e. the magnetic field) changes. It changes only for B and D while in the other cases the field is uniform/constant.
6) (E) -1.5V
e = -Nd(BA)/dt
= -NAdB/dt
= - (10)(0.1)(0.6-0.1)/0.333 = -1.5 V
