A circular loop of flexible iron wire has an initial circumference of 167 cm, but its circumference is decreasing at a constant

Kisachek [45]

Answer:

Part a)

$EMF = 5.6 \times 10^{-3} V$

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction

Explanation:

As we know that magnetic flux linked with the coil is given as

$\phi = \pi r^2 B$

now the rate of change in flux is given as

$\frac{d\phi}{dt} = 2\pi r \frac{dr}{dt} B$

now we know that circumference is decreasing at rate of 15 cm/s

so here we know the length of circumference as

$C = 2\pi r$

So rate of change in circumference is

$\frac{dC}{dt} = 2\pi \frac{dr}{dt}$

$\frac{1}{2\pi}(15 cm) = \frac{dr}{dt}$

final length of circumference at t = 8 s

$C = 167 - (15)(8) = 47$

Part a)

Now the induced EMF is given as

$EMF = (2\pi r)(\frac{1}{2\pi})(0.15)(0.5)$

$EMF = (0.47)(\frac{1}{2\pi})(0.15)(0.5)$

$EMF = 5.6 \times 10^{-3} V$

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction
