Electromagnets can be turned on and off and can conduct electricity.   They are made by coiling wires, and when the electricity is passed the atom lines up.

<h3>What is electromagnetism?</h3>

Electromagnetism studies electromagnets, their behavior, and their uses. Electromagnets are made by coiling the wires that pass the electric current through them making the atoms to line up.

When the charges move across the wires then the magnetic field is created which results in magnetism. The north and south pole like the magnets are created that attracts and repels.

Therefore, electromagnets are studied in electromagnetism.

Kathryn is using cans of juice to fill a cylindrical pitcher that is 11 in. tall and has a radius of 4 in. each can of juice is
Anarel [89]

The number of cans required by Kathryn to fill the pitcher cylinder is 7.3 cans.

<h3>What is volume of cylinder?</h3>

The volume of cylinder is given as the space occupied in the interior of the cylinder. It is given by:

\rm Volume\;of\;cylinder=\pi r^2h

The volume of the cylinder pitcher to be filled is:

\rm Volume\;pitcher=\pi\;\times\;4^2\;\times\;11\;inch^3\\Volume\;pitcher=176\pi inch^3

The volume of one small can is:

\rm Volume\;can=\pi\;\times\;2^2\;\times\;6\;inch^3\\Volume\;can=24\;\pi\;inch^3

The volume given by one can is 24 times pi. The number of cans required to fill the pitcher is:

\begin{aligned} \rm Number\;of\;cans & =\rm \dfrac{Total\;volume}{Volume\;of\;can}\\\\\rm &=\rm \dfrac{176\;\pi\;inch^3}{24\;\pi\;inch^3}\\\\&=\rm 7.3\end{aligned}

Kathryn in order to fill the cylinder required 7.3 cans.
