Fun with Magnets P

materials magnets. Later on the process of making magnets from pieces of iron was discovered. These are known as artificial magnets. Nowadays artificial magnets are prepared in different shapes. For example, bar magnet, horse-shoe magnet, cylindrical or a ball-ended magnet. Fig.13.4 shows a few such magnets. Activity 1 Take a plastic or a paper ...

Magnetic Materials: Soft Magnets

Magnetic Materials: Soft Magnets Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1. They are used primarily to enhance and/or channel the flux produced by an electric current. The main parameter, often used as a figure of

ratio or weaker magnets will require a longer settle time. Remove and discard the clear supernatant. NOTE Care should be taken not to aspirate more than a trace amount of beads during this step, as the desired library is associated with the beads. Significant bead loss will result in reduced yield. 4.
