... The activities in this section provide participants with exposure to the basic properties and behavior of magnets. There are no
prerequisites to this section, although most 4th – 9th grade students (and teachers) have already had experiences with and
learned some facts about magnets. While participa ...

... Some metals, for example iron, steel, cobalt and nickel, are magnetic.
A magnet will attract them. If you drop some steel pins on the floor
you can pick them up using a magnet. A magnetic force is an example
of a non-contact force, which acts over a distance.
In Figure 5.4, you can see a bar magnet ...

... since both were waves. It may be worthwhile to describe one of
the experiments on sound that Faraday did at that time. He
placed a glass jar on a metal plate and partially evacuated the jar.
The plate could be covered with any material, e.g., even liquids,
including some very viscous ones like the w ...

4) Release the magnet and marble at the same time and record your
observations. Repeat several times. Call this test A.

Magnetic nanoparticles are a class of nanoparticle which can be manipulated using magnetic field gradients. Such particles commonly consist of magnetic elements such as iron, nickel and cobalt and their chemical compounds. While nanoparticles are smaller than 1 micrometer in diameter (typically 5–500 nanometers), the larger microbeads are 0.5–500 micrometer in diameter. Magnetic nanoparticle clusters which are composed of a number of individual magnetic nanoparticles are known as magnetic nanobeads with a diameter of 50–200 nanometers. The magnetic nanoparticles have been the focus of much research recently because they possess attractive properties which could see potential use in catalysis including nanomaterial-based catalysts, biomedicine and tissue specific targeting, magnetically tunable colloidal photonic crystals, microfluidics, magnetic resonance imaging, magnetic particle imaging, data storage, environmental remediation, nanofluids, and optical filters, defect sensor and cation sensors.
