A small circular loop of wire of radius 5.0 cm and resistance R = 1.5 10^-3 ohms is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 8.8 A, is cut and its current is reduced to zero over a time interval of 9.0 10^-7 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)

magnitude
direction(clockwise)or(counterclockwise)

Expert Solution

Step 1

We know that the formula of the magnetic field is

$B = \frac{μ_{0} I}{2 r}$

where I is a current

r is the radius of the coil

We also know that the area of the loop is given as

$A = {πr}^{2} A = π \times {(5 \times 10^{- 2})}^{2} A = 7.85 \times \times 10^{- 3} m^{2}$

here A is the Area
