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.
2

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