Two long parallel conductors carries I1 and I2 in opposite directions. Determine the magnetic field between the wires

Eddi Din [679]

Answer:

B1 = μ_o•I1/2πr

Explanation:

According to the right hand rule, we can say that the magnetic field at the second wire due to the current being carried in first wire is given by;

B1 = μ_o•I1/2πr

Where;

r is distance that separates the two wires

μ_o is a constant known as permeability of free space

I1 is current in wire 1

according to Newton's 1st law, in what direction Will an object continue to move if no other outside force acts upon it

asambeis [7]

Answer: <em>An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>

Explanation: meaning, an object will continue in its same direction until stopped or acted upon by another force.

A small, 2.00-mm-diameter circular loop with R = 1.00×10^−2 Ω is at the center of a large 100-mm-diameter circular loop. Both lo

Assoli18 [71]

Answer:

$i=2.1\times 10^{-8}}\ A$

Explanation:

Given that

Diameter of small loop d= 2 mm or r=1 mm

Diameter of large loop D= 100 mm or R=50 mm

We know that induce emf given as

$\varepsilon =-\dfrac{d\phi }{dt}$

$\varepsilon =-\dfrac{BA }{dt}$

$B=\dfrac{\mu _oI}{2\pi R}$

$\varepsilon =-\pi \times r^2\times \dfrac{4\pi \times 10^{-7}(I_2-I_1)}{2\pi Rdt}$

$\varepsilon =-\pi \times 0.001^2\times \dfrac{4\pi \times 10^{-7}(-1-1)}{2\pi \times 0.05\times 0.1}$

$\varepsilon =2.1\times 10^{-10}\ V$

So induce current

i=emf/R

$i=\dfrac{2.1\times 10^{-10}}{10^{-2}}\ A$

$i=2.1\times 10^{-8}}\ A$
