a constant magnetic field of 0.50 T applied to a rectangular loop of area 3.0 x 10^-3 m2. If the area of this loop changes from its original value to a new of 1.6 x 10^-3 m2 in 1.6 s, what is the emf induced in the loop?

Step 1
We know that the magnetic flux (Φ) through the loop is given by the product of the magnetic field (B) and the area (A) of the loop: Φ = B * A. Show more…

A $10 \mathrm{cm} \times 10 \mathrm{cm}$ square loop lies in the $x y$ -plane. The magnetic field in this region of space is $B=\left(0.30 t \hat{\imath}+0.50 t^{2} \hat{k}\right) \mathrm{T}$, where $t$ is in s. What is the emf induced in the loop at (a) $t=0.5 \mathrm{s}$ and (b) $t=1.0 \mathrm{s} ?$
