A 15-turn circular wire loop with a radius of 3.0 cm is initially in a uniform magnetic field with a strength of 0.5 T. The field decreases to zero over a time of 0.10 sec. What is the induced emf?
Added by Ellen S.
Step 1
The magnetic flux through the loop is given by the product of the magnetic field strength, the area of the loop, and the cosine of the angle between the magnetic field and the normal to the loop. Since the magnetic field is uniform and perpendicular to the loop, Show more…

A $0.45-\mathrm{T}$ magnetic field is perpendicular to a circular coil of wire with 53 loops and a radius of $15 \mathrm{~cm}$. If the magnetic field is reduced to zero in $0.12 \mathrm{~s}$, what is the magnitude of the induced emf in the coil? 56. Figure $23.25$ shows the magnetic flux through a wire loop as a function of time. What is the induced emf in the loop at (a) $t=0.050 \mathrm{~s}$, (b) $t=0.15 \mathrm{~s}$, and (c) $t=0.50 \mathrm{~s}$ ?
