PPT-Magnetic stirrer

By Mayu amp Emma 2 What is it for A magnetic stirrer is used to stir liquids faster The stirrer is a little magnetic plastic piece shaped like a pill that interacts with a magnet located in the plate below the container It is used to make the pill spin very fast which is better if you want to make things dissolve quickly. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir The tip can be adjusted allowing the user to measure fields that are parallel or perpendicular to the long axis of the sensor The Magnetic Field Sensor can be used for a variety of interesting experiments involving magnetic fields Measure and study Fold spacecraft body along white lines to make a cube. … force in . direction. … . sample volume. … magnetic . susceptibility. … magnetic field. … gradient of . the magnetic . field.  .

Research that has been done on this has shown that . the . heat from the heated hydrogen peroxide creates more kinetic energy, making the enzymes move faster in the solution so they collide with more substrates, creating a faster reaction. The opposite is present with the cold water, slowing the enzymes, so they collide at a slower rate. The room temperature would act as a control to see how everything would compare versus normal conditions.. 1. Hori et al.. Preparation . of.
