Question

Suppose that a rectangular toroid has 1,500 windings and a self-inductance of 0.060 H. If the height of the rectangular toroid is h = 0.80 m, what is the current (in A) flowing through the rectangular toroid when the energy in its magnetic field is 9.0 ✕ 10−6 J?

Answer 1

Current in the toroid will be
`I=17.32* 10^(-3)A`

Step-by-step explanation:

We have given number of winding in rectangular toroid N = 1500

Self inductance of toroid L = 0.06 H

Magnetic energy stored in toroid
`E=9* 10^(-16)J`

We have to find the current in the toroid

Magnetic energy stored is equal to
`E=(1)/(2)Li^2`

`9* 10^(-6)=(1)/(2)* 0.06* I^2`

`I=17.32* 10^(-3)A`

So current in the toroid will be
`I=17.32* 10^(-3)A`
