  A comparative study of the growth of S.aureus in different types of weak
magnetic field shows that the growth of the bacteria is initially suppressed
after inoculation in a new medium and then increased in the same pattern with
or without magnetic field. However, the rate of growth and death of bacteria
depend on the variation in the magnetic field for comparable strength. Magnetic
field effect on the ionic motion plays a key role in the growth rate. It is
shown that the concentration of bacteria reduces initially and then it starts
increasing after some time. Multiplication and death of bacterial cells is
related to its interaction with the nutrients which is managed by the magnetic
field direction, strength and variation at room temperature.
