Question

Suppose that a rectangular toroid has 2,000 windings and a self-inductance of 0.060 H. If the height of the rectangular toroid is h = 0.60 m, what is the current (in A) flowing through the rectangular toroid when the energy in its magnetic field is 4.0 ✕ 10−6 J?

Answer 1

0.01154 A

Step-by-step explanation:

We have given the energy in the magnetic field
`U=4* 10^(-6)J`

Value of inductance L =0.060 H

Energy stored in magnetic field is given by
`U=(1)/(2)Li^2`

`i=\sqrt{(2U)/(L)}`

`i=\sqrt{(2* 4* 10^(-6))/(0.06)}=0.01154\ A`

So the current flowing through rectangular toroid will be 0.01154 A
