A wire of radius 0.35 cm carries a current of 75 A that is uniformly distributed over its cross-sectional area. The magnetic field 0.20 cm from the center of the wire is approximately

Respuesta :

Answer:

The value is  [tex]B =  0.00122 \  T [/tex]

Explanation:

  The radius  is  [tex]r =  0.35 \  cm  = 0.0035 \  m[/tex]

  The current is  is [tex]I  =  75 \  A[/tex]

 The position considered is  [tex]x = 0.20 \ cm  =  0.002 \ m[/tex]    

Generally the magnetic field  0.20 cm from the center of the  wire is mathematically represented as

     [tex]B =  \frac{\mu_o  *  I  *  x}{4 \pi *  r^2}[/tex]

Here [tex]\mu_o[/tex] is the permeability of free space with value

          [tex]\mu_o =  4\pi * 10^{-7} \  N/A^2[/tex]

Generally

        [tex]B =  \frac{4\pi * 10^{-7}  *  75  *  0.002 }{4*  3.142 *  (0.0035)^2}[/tex]

=>      [tex]B =  \frac{4\pi * 10^{-7}  *  75  *  0.002 }{4*  3.142 *  (0.0035)^2}[/tex]

=>      [tex]B =  0.00122 \  T [/tex]

The value of the megnetic field will be 0.00122 T.It is the kind of domain where the magnetic force is received.

What is a magnetic field?

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

r is the radius= 0.35 cm= 0.0035 m

I is the current = 75 A

x is the position considered = 0.20 cm=0.002 m

The megnetic field is found as;

[tex]\rm B= \frac{\mu_0 Ix }{4 \pi r^2} \\\\ \rm B= \frac{4 \pi \times 10^{-7} \times 75 \times 0.002 }{4 \pi (0.0035)^2} \\\\ \rm B=0.00122\ T[/tex]

Hence the value of the megnetic field will be 0.00122 T.
