The question I want you to complete is the one in the middle number 3 please

Answer 1

I = 50 A

Step-by-step explanation:

The magnetic field created by a wire with a current can be calculated as:

`B=(\mu I)/(2\pi r)`

Where μ is a constant equal to 4π x 10^(-7) T m/A, I is current, and r is the distance from the wire. So, replacing the values, we get:

`0.005=(4\pi*10^(-7))/(2\pi(0.002))I`

Then, solving for I, we get:

`\begin{gathered} 0.005=0.0001I \\ (0.005)/(0.0001)=(0.0001I)/(0.0001) \\ 50A=I \end{gathered}`

Therefore, the current that is traveling through the wire is 50 A.

On the other hand, if the current is moving upward, the direction of the magnetic field can be found by the rule of the right hand, so the magnetic field will have the following direction:
