find the magnetic induction at the centre of a circular Coil of radius 0.1m having 50 turns and carrying a comment of 500 mA.
Answers
Answer:
magnetic field on the axis of circular loop is given by,
where N is number of turns , i is current through circular coil or loop , x is distance between point of observation to center of circular coil, R is the radius of circular coil.
here, N = 50, i = 1A , R = 0.05m and x = 0.2m
and we know, mkg/s²A²
so, B = (4π × 10^-7 × 50 × 1 × 0.05²)/(0.2² + 0.05²)^3/2
= 0.0000179 Weber/m²
= 1.79 × 10^-5 Weber/m²
hence, magnetic field is 1.79 × 10^-5 Weber/m²
