Answer:

The magnetic field at the center of a circular loop is
$3.14*10^(-5)\ T$ .

Step-by-step explanation:

Given that,

Radius = 4.0 cm

Current = 2.0 A

We need to calculate the magnetic field at the center of a circular loop

Using formula of magnetic field

$B = (I\mu_(0))/(2r)$

Where, I = current

r = radius

Put the value into the formula

$B =(2.0*4\pi*10^(-7))/(2*4.0*10^(-2))$

$B =0.00003141\ T$

$B=3.14*10^(-5)\ T$

Hence, The magnetic field at the center of a circular loop is
$3.14*10^(-5)\ T$ .
