An inductor in the form of an air-core solenoid contains 191 turns, is of length 17.9 cm, and has a cross-sectional area of 1.2 cm^2 . the permeability of free space is 1.25664 × 10^−6 n/a^2 . what is the magnitude of the uniform rate of change in current through the inductor that induces an emf of 205 µv? answer in units of a/s.

The magnitude of the uniform rate of change in current through the inductor is 13.66 A/s.

Explanation:

To find the magnitude of the uniform rate of change in current through the inductor we will use the formula:

ΔI/Δt = e×l / μ0×N×A

Now, put all the given  values in this formula and then you will get your answer,

ΔI/Δt = 205×10^-6×19.2 / 1.2566×10^-6×191×1.2

ΔI/Δt = 13.66 A/s.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
