Question

16. Evaluate the magnetic field intensity at point
P2 (4,2,0) due to current carrying conductor of
21 a, u Am placed at point P1(0,0,2).​

Answer 1

Answer:

The Biot Savart law is used for computing the resultant magnetic field B at position r generated by a steady current I.

According to it

B=

4π

.

So magnetic field at a distance r due to the current carrying conductor depends on:

i) the value of current

ii)small part of length of conductor

iii) and, the angle between the line joining the given point to the mid point of small length and the distance between the small length of the point.
