A single-turn circular loop of radius 14 cm is to produce a field at its center that will just cancel the earth's magnetic field at the equator, which is 0.7 g directed north. the permeability of free space is 4 π × 10−7 t · m/a. find the current in the loop. answer in units of a

49 A

Explanation:

We are given that

Number of turns,N=1

Radius,r=14 cm=

1 m=100 cm

Magnetic field,B=0.7 G=

We know that magnetic field

Substitute the values

i need to show me the graph so i can give u an answer
