To determine the poles of an unmarked magnet, you can use a known magnet or a compass. Bring the compass close to the magnet; the compass needle will point towards the magnet's south pole, as it is attracted to the north pole of the compass. Alternatively, you can use another magnet: the north pole of the second magnet will be attracted to the south pole of the unmarked magnet and repelled by its north pole. This interaction can help you identify the poles of the unmarked magnet.

Why is the earth's magnetic north pole really a magnetic south pole?

The north pole of a magnet is defined as that pole which is attracted to the Earth's magnetic pole. Since opposite poles attract that would, indeed, make the Earth's Northern hemisphere pole a magnetic south pole.Another AnswerLet's start by sorting out the terminology. 'Magnetic North' is a location, so-called, to distinguish it from 'True North'. It is not the magnetic polarity of that location. Magnetic North is not a fixed location, but is always moving relative to Magnetic North which is located at the earth's axis.A freely-suspended magnet, when it comes to rest, essentially points towards Magnetic North (it actually lies along the lines of magnetic flux that join Magnetic North and Magnetic South). For this reason, that end of a magnet (and that of a compass needle) was originally called its 'North-seeking' pole. Over time, we have dropped the word, 'seeking', and it's now simply called its 'north pole' and, by common agreement, this is also considered to be its magnetic polarity.So, if the 'north' pole of a magnet points towards the location we call 'Magnetic North', then the magnetic polarity of that location is a south pole. This is because unlike poles attract.So, to answer the question, the south magnetic pole of the earth is located (deep within the earth) below the located we call 'Magnetic North' in Canada.Why people find this so confusing can only be put down to poor teachers!Read more: Where_is_the_south_magnetic_pole_of_the_earth


What is the difference between a strongly magnetized nail and a weakly magnetized nail?

In an un-magnetised nail there are tiny domains, each in themselves would be a little magnet, however, in a magnetized steel nail the magnetic "domains" tend to be lined up in the same direction. A domain is a tiny magnet because electrons are spinning with the same orientation. Refer to the related link in the Related Links section below for more details.

Which marking is required on a shipment of 5 L of Kerosene packaged in accordance with packing instruction Y344?

Shipments of 5 L of kerosene packaged according to packing instruction Y344 must be marked with the appropriate UN number, which is UN 1223, and the proper shipping name "Kerosene." Additionally, the package should display the hazard class label for flammable liquids (Class 3), along with any other required markings such as handling and orientation labels as specified by relevant regulations.


Is F2 paramagnetic?

Yes! Since it has un-paired electrons: ) Actually C2 isn't paramagnetic. There's certain type of diagram how to determine whether molecule is paramagnetic or not. And C2 isn't. Instead C2(2+) would be paramagnetic.
