Matter can be classified into two basic categories. Matter is either a mixture or it is a pure substance.

Answer:

$7.3114*10^{-5}V$

Explanation:

To give a solution to the exercise, it is necessary to consider the concepts related to magnetic flux and Faraday's law of induction. Faraday's law states that the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time.

It is represented under the equation,

$\epsilon = N \frac{\Delta\Phi}{\Delta t}$

Where,

$\epsilon$ is the induced electromotive force

N = Number of loops

$\Delta t$ = Time

$\Delta\Phi$ = Magnetic Flux

For definition the change in magnetic flux is:

$\Delta \Phi = \Delta B A cos\phi$

Where,

B= Magnetic field

Substituting at the first equation we have

$\epsilon = N \frac{\Delta B A Cos\phi}{\Delta t}$

$\epsilon = N \frac{(B_2-B_1) (\pi r^2) Cos\phi}{\Delta t}$

Our values are given by,

N = 1 turn

$B_2 = 1T$

$B_1 = 0T$

r = 1.6mm

$\phi = 0\°$

$\Delta t = 100ms$

Replacing,

$\epsilon = (1) \frac{(1-0) (\pi (1.6*10^{-3})^2) Cos(0)}{110*10^{-3}}$

$\epsilon = 7.311*10^{-5}V$

<em>Therefore the magnitud of the induced emf around a horizontal circle of tissue is $7.3114*10^{-5}V$ </em>

Answer:

675 A

Explanation:

B = 1.5 x 10^-8 T

r = 9 km = 9000 m

Let the current be i

The formula for the magnetic filed due to a very long straight conductor is given by

$B =\frac{\mu_{0}}{4\pi }\times \frac{2i}{r}$

$1.5\times 10^{-8} =10^{-7}\times \frac{2i}{9000}$

i = 675 A
