Answer 1

Answer:

Magnetic field at the center will be $215.314\times 10^{-7}T$

Explanation:

We have given that diameter of the loop d = 14 cm = 0.14 m

So radius $R=\frac{d}{2}=\frac{0.14}{2}=0.07m$

Current in the loop i = 2.40

We know that magnetic field at center of circular loop is given by

$B=\frac{\mu _0i}{2R}$

So $B=\frac{4\pi \times 10^{-7}\times 2.4}{2\times 0.07}=215.314\times 10^{-7}T$

Magnetic field at the center will be $215.314\times 10^{-7}T$
