Amagnetic field of magnitude 1.30x10-3 t is measured a distance of 0.03 m from a long straight wire. what is the current through the wire?

Explanation:

According to the Biot–Savart law, the magnitude of a magnetic field created by the current in a long straight wire, is defined as:

Where is the permeability of free space, I is the current circulating on the wire and R is the distance from the point where B is measured.

Solving for I:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
