Question
A long, straight wire lies in the plane of a circular coil with aradius of 0.050 m. The wire carries acurrent of 6.0 A and is placed along adiameter of the coil. (a) What is the net flux through the coil?1
(b) If the wire passes through the center of the coil and isperpendicular to the plane of the coil, find the net flux throughthe coil.
2 (a) What is the net flux through the coil?

Explanation / Answer
(a) What is the net flux through the coil?1
zero.
(b) If the wire passes through the center of the coil and isperpendicular to the plane of the coil, find the net flux throughthe coil.

B=2*3.14*10-7*5/0.020=1570wb/sq.m
flux=BA
1570*3.14*0.02*0.02=1.97192weber.
