Step 1
The magnetic flux is given by the equation: Ī¦ = B * A where Ī¦ is the magnetic flux, B is the magnetic field, and A is the area of the loop. In this case, B = 0.50 T and the area of the loop is increasing at a rate of 3.0 x 10^-3 m^2/s. So, we can write: dĪ¦/dt Show moreā¦

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?

A circular loop with a radius of 2.5 m rests horizontally inside a uniform magnetic field of 0.9 T in a down direction. What is the induced emf when the magnetic field drops to zero in 0.75 s?

A wire loop of radius $0.30 \mathrm{~m}$ lies so that an external magnetic field of magnitude $0.30 \mathrm{~T}$ is perpendicular to the loop. The field reverses its direction, and its magnitude changes to $0.20 \mathrm{~T}$ in $1.5 \mathrm{~s}$. Find the magnitude of the average induced emf in the loop during this time.
