A current of 5 A flows through a circular coil with 500 turns and radius of 15 cm . Find the magnetic induction
1 at the center of the coil
2. at a point 10 cm from the center on the axis of the coil.

B = μ N I / [2r] = 4*π*1e- 7*500* 5 / 30 e-2 = 1.046 e-2 tesla
--------------------
B = μ N I / [2(x^2 + r^2] ^ 1.5 = 4*π*1e- 7*500* 5 / [2(0.1^2 + 0.15^2] ^ 1.5
= 62X10^-5 tesla
