Question

What is the general formula for measuring
`\vec{B}` , i.e. , magnetic field intensity ?

tysm ;-;

Answer 1

#include <stdio.h>

int main()

{

const int LENGTH = 10;

const int WIDTH = 5;

const char NEWLINE = '\\';

int area;

area = LENGTH * WIDTH;

printf("value of area : %d", area);

printf("%c", NEWLINE);

return 0;

}

Answer 2

Step-by-step explanation:

`{ \rm{ \vec{B}} = ( \mu_(0)N)/(l) } \\`

N is number of turns

l is conductor length

mu_0 is permeability

`{ \boxed{ \tt{ \mu_(0) = 4\pi * {10}^( - 7) }}}`
