Towards the end of the year, the weather in Seville starts to become slightly milder. In October, the sun shines for at least 7 hours per day but brace yourself for rain as there are on average 6 days of rainfall during the month.
When a molecule has no dipole moment, like CO2, then it is nonpolar. When a molecule has a dipole moment like water, then it is polar. This polarity business is very important. Polar molecules are like little magnets, with a positive end and a negative end, and they interact with each other through magnetic attractions.
As such, the SI unit of magnetic dipole moment is ampere metre 2. More precisely, to account for solenoids with many turns the unit of magnetic dipole moment is Ampere-turn metre 2. In the Gilbert model, the magnetic dipole moment is due to two equal and opposite magnetic charges that are separated by a distance, d.
