Question

Two long parallel wires carry currents of 20 A and 5.0 A in opposite directions. The wires are separated by 0.20 m. What is the magnetic field midway between the two wires

Answer 1

The magnetic field midway between the two wires is $5.0*10^{-7} T$.

It is given that Two long parallel wires carry currents of 20 A and 5.0 A in opposite directions. The wires are separated by 0.20 m.

We need to determine the magnetic field midway between the two wires.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

Magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge.

B=B1+B2

=$\frac{4\pi *10^{-7}*20 }{2\pi R1} +\frac{4\pi *10^{-7}*5 }{2\pi R2}$

= $\frac{4\pi *10^{-7}*20 }{2\pi *0.10} +\frac{4\pi *10^{-7}*5 }{2\pi *0.10}$

= $5.0*10^{-7} T$

Hence, the magnetic field midway between the two wires is $5.0*10^{-7} T$
