Answered

a solenoid has 15 turns per centimeter of its length. the solenoid is twisted into a circle so that it becomes shaped like a toroid. what is the magnetic field at the center of each turn of the toroid? the current is 29 mama .



Answer :

The magnetic field at the center of each turn of toroid is: 2.826×10⁻⁵ T

What is a magnetic field?

Magnetic field is a vector field in surrounding of a magnet, electric current carrying conductor or a changing electric field, in which magnetic forces can be experienced.

Magnetic field of a toroid is calculated as (B): μ₀nI

Where, μ₀= permeability

n= Number of turns in toroid

I= Current

B= Magnetic field

In the given question,

n=15 turns/cm

I=15mA

Now turns per meter length is: 15/10⁻²=1500turns per meter

The magnetic field at the center of each turn of the toroid is(B): μ₀nI

B= (4[tex]\pi[/tex]×10⁻⁷)(1500)(15×10⁻³A)

B= 2826×10⁻⁸ T

B= 2.826×10⁻⁵ T
