Paramagnetism
The paramagnetic properties of oxygen are demonstrated using a strong magnet, and compared with diamagnetic nitrogen.

Paramagnetism: Compounds
Vials of a number of compounds (NaCl, MnSO4, FeSO4, CoCl2, NiSO4, ZnSO4, K4Fe(CN)6, [Co(NH3)6]Cl3, [Ni(NH3)6]Cl2, and H2O) are hung from a thread. When a magnet is brought near, some of the vials are attracted.

Paramagnetism: Oxidation States of Manganese
Manganese(III) oxide, with 4 unpaired electrons per Mn atom, is more strongly attracted to a magnet than is manganese(IV) oxide, with only 3 unpaired electrons per Mn atom. Potassium permanganate, a compound of Mn(VII), has no unpaired electrons and is not attracted to a magnet.

Electricity and Magnetism ? A Dynamic Duo
When using a compass to see which way is north, south, east, and west, we are really using a magnet. The little moving pointer in a compass is actually a small magnet! Electricity in a wire can also be used to make a magnet. Students investigate this relationship by setting up a wire and making the magnetism from the electricity in the wire move the magnet in the compass.

Magnets Point the Way
We use a compass to see which way is north, south, east, and west. When we use a compass we are actually using a magnet. The little moving pointer in a compass is actually a small magnet. The needle lines up and points in a certain direction because Earth itself has magnetism and acts like a magnet too. Students investigate to learn how a compass works.

Metals and Magnetism
Metals are the only substances that are magnetic. The most,common magnetic metal is iron. Although few products are made of pure iron, a lot of products are made of steel. Since steel has a lot of iron in it, steel is attracted to a magnet. In this activity students investigate a wide range of materials to discover which ones are magnetic and which are not.

Paramagnetism (GCMP) David M. Whisnant
Paramagnetism: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will begin by observing the magnetism of three manganese compounds. These compounds have been placed in capsules, which will be pulled toward a magnet if the compound is paramagnetic. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
