A segment of wire of total length 2.0 m is formed into a circular loop having 5.0 turns. If the wire carries a 1.2-A current, determine the magnitude of the magnetic field at the center of the loop.

Magnetic field at the center of the loop

Explanation:

It is given that total length of wire is 2 m and number of circular loop is 5 turns.

Therefore ,

We know , magnetic field at the center of loop is given by :

Putting all values in above equation we get :

Hence , this is the required solution.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

this could be newton#'s law of cooling. the cooling curve is exponential
