Magnetic Fields in Matter

Para and Diamagnetism

[L | t+ | ★★★]
Testing a selection of compounds for magnetic susceptibility, by suspending them between the poles of an electromagnet.
[In-Depth Description]

Diamagnetic Levitation

[S | t+ | ★★★]
Stable levitation of one magnet by another is usually prohibited by Earnshaw's Theorem, but the introduction of diamagnetic material at special locations can stabilize such levitation.

Paramagnetism of Oxygen

[S/M | t++ | —]
Liquid O2 is attracted to the poles of a permanent magnet.
[In-depth description]

Image Current

[L | t+ | ★★★]
An image current is created in a ferromagnetic material in the presence of a real current.
[In-depth description]


[M/L | t+ | —]
Hysteresis loops of iron and ferrite are displayed on CRO.

The Barkhausen Effect

[M | t+ | ★★★]
Hear the sound of magnetic domains aligning as a bar magnet is brought towards iron sample.
[In-Depth Description]

Magnetic Bubbles

[S | t+ | ★★]
Wafer thin magnetic garnet under microscope reveals direction of magnetic domain alignment as light and dark pattern.
[In-Depth Description]

Bar Magnet Domains

[S | t | —]
Magnetic domains are modeled on the OHP.

Curie Point

[M | t+ | —]
Iron wire is not attracted to a magnet when its temperature is raised above 770 deg. C.

Hall Effect

[s | t++ | ★★★]
The Hall voltage of a semiconductor is measured as a function of applied magnetic field.
