Question

A wire wrapped around a toroid has inner radius of 10.0 Cm and an outer radius of 20.0 Cm. if the wire wrapping makes 800 turns and carries a current of 10.0 A . what are the maximum or minimum values of magnetic field within the toroid​
PLEASE I WILL mark as BRAINLIST

Answer 1

Answer:

12mT,6mT

Explanation:

Here inner radius of toroid, r1=10×10−2m

Outer radius of toroid, r2=20×10−2m

Bmax=μ0N2πr1I=(4π×10−7)×600×102π×(10×10−2)

=12×10−3T=12mT

Bmin=μ0N2πr2I=(4π×10−7)×600×102π×(20×10−2)

=6×10−3T=6mT

there is a question mistake it will be 600 turns if you will take 8000 turns its answer will come in point , so make question correct .

nice to help you
