Question

A iron ring 8cm mean diameter is made up of round ring of diameter 1cm and permiability of 900 has an air gap of 2mm it consits of coil carrying current of 3.5 A determine flux

Answer 1

The flux is 12600 Tesla.

Given:

Diameter of wire = 8 cm = 0.08 m

Radius of wire = 0.04 m = R

Diameter of ring = 1 cm = 0.01 m

Radius of ring = 0.005 m = r

Permeability = 900 = μ

Current flowing through coil = 3.5 A = I

Explanation:

The magnetic flux is given by the formula:

Φ = B × A

Where,

B = Flux density = μ × H = μ × I/(2πr)

A = Area = πR²

Now, the flux is given as:

Φ = μ × I/(2πr) × πR²

On substituting the values, we get,

Φ = 900 × 3.5/(2 × 22/7 × 0.005) × 22/7 × 0.04

∴ Φ = 12600 T
