The average radius of a toroid made out of a nonmagnetic material is $0.1 m$ and it has $500$ turns. If it carries $0.5 A$ current, then the intensity of the magnetic field along its circular axis in $Tesla$ will be

Options:

Answer:

Solution:

$N = 500$

$R = 0.5 A$

$r = 0.1 m$

for toroid

$B = \frac{μ_{0} N I}{2 π r}$

$B = \frac{4 π \times 1 0^{- 7} \times 500 \times 0.5}{2 π \times 0.1}$

$B = \frac{500 \times 5}{1 0^{7}} = 2.5 \times 1 0^{- 4} Tesla$
