alexdok [17]
<h2>Answer: Ion </h2>

An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons. </u>

To understand it better:

An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.

In this sense, there are two types of ions:

-Anions: ions negatively charged, by the gain of electrons in the atom.

-Cations: ions positively charged, by the loss of electrons in the atom.

pshichka [43]

Answer:

F = BIl

F » magnetic force

B » magnetic flux density

l » length / circumference

F = BI(2\pi r)

r » radius

F = 2 \times 5 \times (2 \times 3.14 \times 0.05) \\ { \underline{force = 3.14 \:  \: newtons}}
