The magnetic field is

2.288 \times 10 {}^{ - 6} T

what is magnetic field?

Magnetic field is defined as the relationship between the permittivity of free space,the magnitude of electric current,and distance.

Here is the formula,

B =  \frac{µ0l }{2π R}

here,

B= magnitude of the magnetic field

l= magnitude of electric current

R=distance

µ0=permittivity of free space

Now,using above formula we can calculate the magnetic field

B =  \frac{µ0l }{2π R}

\frac{4\pi \times 10 {}^{ - 7}. \frac{m}{a}  \times 103 }{2\pi \times (9m)}

= 2.288 \times 10 {}^{ - 6} T

Thus,the magnetic field is

= 2.288 \times 10 {}^{ - 6} T

The current in a hair dryer measures 15 amps. The resistance of the hair dryer is 14 ohms. What is the voltage?
ZanzabumX [31]
We have that there is a formula connecting these three. V=I*R where V is voltage, I is the current and R is the resistance. Substituting, we get that V=210 Volta, which is the unit of measurement for voltage. You can think of the relationship in the following way : The energy of the field is equal to the flow of the field times the resistance that it meets.
