Magnetic field due to currentHard
Question
Current i = 2.5 A flows along the circle x2 + y2 = 9 cm2(here x & y in cm) as shown. Magnetic field point (0, 0, 4 cm) is
Options
A.(36π × 10-7T) 
B.(36π × 10-7T) -
C.
D.
Solution
Magnetic file on the axis of a circular loop
B =
= 10-7 × 
= (36π × 10-7T)
B =
= 10-7 × = (36π × 10-7T)Create a free account to view solution
