As Shown Below, a Square Loop of Wire of Side

question 16

Multiple Choice

As shown below, a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity directed to the right. Judd says that the emf induced in the loop is zero. Roger claims that it has magnitude B . Which one, if either, is correct, and why? ​
​ ​

• A)Judd, because the magnetic flux through the loop is constant.
• B)Roger, because the magnetic flux through the loop is constant.
• C)Judd, because the magnetic flux through the loop is not constant if .
• D)Roger, because the magnetic flux through the loop is not constant if .
• E)Roger, because the magnetic flux through the loop is ΦB = 0.
