Linear velocity and angular velocity are related by the formula:
v = ωr

ω = n2πr/t, where n is the number of rotations, t is the time taken, r is the radius.
ω = 2 x 2π x 25/1
ω = 100π

v = 100π x 25
= 2500π feet per minute

Calculate the magnetic field at 2m from a straight wire carrying a current of 5 A. (K = 2 x 10 ^-7)

blagie [28]

Answer:

$B=5\times 10^{-7}\ T$

Explanation:

Given that,

Current in a wire, I = 5 A

We need to find the magnetic field at 2m from a straight wire carrying a current of 5 A.

The magnetic field due to a wire is given by :

$B=\dfrac{\mu_0I}{2\pi r}\\\\B=\dfrac{4\pi \times 10^{-7}\times 5}{2\pi \times 2}\\\\B=5\times 10^{-7}\ T$

So, the required magnetic field is $5\times 10^{-7}\ T$ .
