Magnetic field shielding / Abd Halim Mohamed Isman

Electromagnetic Interference (EMI) is an unwanted disturbance. Due to this, necessaiy prevention should be taken. This report describes a study on the magnetic shielding of EMI emitted from a step down transformer. Gaussmeter with frequency range 30 to 300Hz is used to measure the strayed magnetic field. Various experimentations had been conducted in terms of shielding materials, methods and locations. From the experiments, the most suitable material that provides the best shielding effectiveness could be discovered. Results indicated that the material with high permeability value and suitable thickness is the most important factor for proper magnetic shielding.
