Magnetic field due to currentHard
Question
The magnetic field due to a current carrying circular loop of radius 3 cm at a point on the axis at a distance of 4 cm from the centre is 54 μT. What will be its value at the centre of the loop?
Options
A.250 μT
B.150 μT
C.125 μT
D.75 μT
Solution
Using formula B = 
, we get
54 =
....(i)
At the centre of the coil, X = 0 and B =
Using equation (i)
B =
⇒ B = 250 μT.
