Question
A conducting wire shaped in a “U shape” is connected to a 5 ohm light bulb.
The 0.8 T external magnetic field is directed into the page as shown.
A conducting bar of length 1.2 m is sliding on the conducting wire at 2 m/s to the right. What is the induced emf?
Hint: the induced emf is the negative of the change in magnetic flux. The magnetic flux changes because the area of the U shaped wire placed in the magnetic field changes when the conducting wire slides to the right.
Induced emf <=> emf = -N ∆Φ/∆t
∆Φ =∆(BA)= B ∆A =B ( Af-Ai)
Group of answer choices
A) 1.92 V
B) 0.8 V
C) 2.4 V
D) 6.8 V
