An experiment on the earth's magnetic field is being carried out 1.00 m from an electric cable. what is the maximum allowable current int eh cable if the experiment is to be accurate?

The allowed current in the cable is 1.15 A.

Explanation:

Given that,

Distance = 1.00 m

Suppose the magnetic field is and  if the experiment is to be accurate to 1.0 %

We need to calculate the current

Using formula of magnetic field

Put the value into the formula

If the experiment is to be accurate to 1.0%

Then,

We need to calculate the allowed current in the cable

Hence, The allowed current in the cable is 1.15 A.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
