Answer:
Approximately
(approximately
) assuming that the magnetic field and the wire are both horizontal.
Explanation:
Let
denote the angle between the wire and the magnetic field.
Let
denote the magnitude of the magnetic field.
Let
denote the length of the wire.
Let
denote the current in this wire.
The magnetic force on the wire would be:
.
Because of the
term, the magnetic force on the wire is maximized when the wire is perpendicular to the magnetic field (such that the angle between them is
.)
In this question:
(or, equivalently,
radians, if the calculator is in radian mode.)
.
.
.
Rearrange the equation
to find an expression for
, the current in this wire.

FULL ANSWER
Neutrons and protons make up a nucleus and they are in the middle of an atom. Electrons surround the nucleus. Opposite charges attract each other. Because of this, protons do not attract other protons and electrons do not attract other electrons. Instead, protons attract electrons and electrons attract protons. When someone looks at the elements on the periodic table, they can see how many protons are present by looking at the atomic number. Since atoms have to have an equal amount of each, if an element contains 36 protons, it also has 36 electrons.
Answer:Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth's Moon.❤
