Answer 2

The magnetic field at the center of a square loop is $3\times10^{-7}\ T$

Explanation:

Given that,

Current = 1.5 A

Length = 50 cm

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

Using formula of magnetic field

$B=\dfrac{\mu_{0}I}{4\pi\times a}(\sin\theta+\sin\phi)$

Where, a = side

I = current

Put the value into the formula

$B=\dfrac{4\pi\times10^{-7}\times1.5}{4\pi\times25\times10^{-2}}(\sin45+\sin45)$

$B= 3\times10^{-7}\ T$

Hence, The magnetic field at the center of a square loop is $3\times10^{-7}\ T$
