A long straight wire carrying a current of 2.74 A moves with a constant speed v to the right. A 5 turn circular coil of diameter 12.5 cm, and resistance of 3.25 „2, lies stationary in the same plane as the straight wire. At some initial time the wire is to the left of the coil at a distance d = 3.00 cm from its center. 7.00 s later, the wire has moved to the right of the coil and is at a distance d from the center of the coil. What is the magnitude and direction of the induced current in the coil?

Question
Transcribed Image Text:A long straight wire carrying a current of 2.74 A moves with a constant
speed v to the right. A 5 turn circular coil of diameter 12.5 cm, and
resistance of 3.25 µ2, lies stationary in the same plane as the straight wire.
At some initial time the wire is to the left of the coil at a distance
d = 3.00 cm from its center. 7.00 s later, the wire has moved to the right of
the coil and is at a distance d from the center of the coil. What is the
magnitude and direction of the induced current in the coil?
0.04926
What is the change in magnetic flux inside the coil due to the
straight wire? How does Faraday's law relate this change in flux to
the induced emf? mA
