Question

A coil of 100 turns,5 cm2 area is placed in external magnetic field of 0.2 tesla in such a way that it makes an angle 30 with the field direction.Calculate magnetic flux through the coil.

Answer 1

Answer:

The magnetic flux through the coil is 8.6 * 10⁻³ Wb

Explanation:

Given data:

No. of turns, N = 100

Area of cross-section, A = 5 cm²= 5 * 10⁻⁴ m²

Magnetic field, B = 0.2 T

Angle, θ = 30°

To find: magnetic flux of the coil, ∅

The magnetic flux is given by,

∅  = N*B*A*cosθ  

∴ ∅ = 100 * 0.2 * 5 * 10⁻⁴ * cos 30°

or, ∅ = 100 * 5 * 10⁻⁴ * 0.2 * 0.866

or, ∅ = 86.602 * 10⁻⁴

or, ∅ = 8.6 * 10⁻³ Wb

Answer 2

Answer:

Explanation: hope you get it well the theta has to be between area vector and the magnetic field
