Astraight wire of length 0.53 m carries a conventional current of 0.2 amperes. what is the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire? use both the exact formula and the approximate formula to calculate the field. (a) result using exact formula

Explanation:

It is given that,

Length of wire, l = 0.53 m

Current, I = 0.2 A

(1.) Approximate formula:

We need to find the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire, r = 2 cm = 0.02 m

The formula for magnetic field at some distance from the wire is given by :

B = 0.000002 T

(2) Exact formula:

B = 0.00000199 T

or

B = 0.000002 T

Hence, this is the required solution.

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 .!

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
