The Effect of Magnetic Field Exposure on The Growth of Green and Red Spinach Plants

Abstract

A magnetic field is defined as the space around a magnet that is still experiencing a magnetic force. As the electric force, the magnetic force is driven by something, namely a magnetic field. A moving charge creates a magnetic field which in turn exerts a force on another moving charge. This study aims to determine the effect of magnetic fields exposure on the growth of spinach plants. The increase in demand for spinach in Indonesia has not been matched by the availability of sufficient spinach, one of the reasons for the insufficient availability of spinach is the decrease in fertile land for agriculture. This causes the ability to produce spinach planted in the ground also decreases. This study uses materials that are easily obtained, the method used in this research is quantitative research with a true experimental design, in the form of  magnetic field exposure on the growth rate of spinach plants. The magnetic field used is produced from the coils of copper wire with the number of 5, 20, 35, 50 and 0 widing, with the duration of exposure was 30 minutes every day for 7 days. Magnetic fields in water exposed whare soaking spinach seeds rested which increases the permeability of the seed film, activates calcium ions, and inhibits the growth of microorganisms in water that are harmful to seed germination and plant growth. From the results of this study indicate that the use of copper wire with the number of widing is still not optimally used.
