The region around a magnet where the magnetic force is exerted is known as its lodestone. magnetic field. magnetic pole. magnetic domain.

magnetic field.

Explanation:

think of the earth. it has a north and south pool. the earth stays together due to the magnetic pull from the center of the earth. to answer that question why would the north pool be called north pool. that is the center, the magnetic force it makes is the magnetic field.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
