MAGNETISM AND SAFETY UNIT |
The exploration of magnetic phenomena necessitates a comprehensive understanding of both the fundamental principles governing magnetic fields and the potential hazards associated with their application, particularly in the context of human exposure and technological implementation.
Magnetic field distribution is dangerous because it cannot be seen directly; only the magnetic force acting on magnetizable materials can be sensed.
Materials exhibit diverse magnetic properties based on their susceptibility, which dictates how they respond to applied magnetic fields. These properties determine their suitability for various applications, ranging from biomedical engineering to industrial manufacturing.
In technology the transparency of most materials to magnetic fields has allowed the introduction of permanent magnets and electromagnets in a wide range of applications. To mention only those the Unit is interested at the moment, RFID, Witricity, Tesla Coils, Autotransformers, Contactless Magnetic sensors and remote actuation systems based on magnetic fields, which are critical for handling explosive gases.
Some Notable Projects
The main topic of the unit is the design of a parahydrogen hyperpolariser coil for enhancing the signal to noise of NMR devices. The Project NMR-4-Tropic discussed at a nuclear level the enhancement obtained by using hydrogen molecules in non magnetically equivalent states. The use of parahydrogen is a novel approach to improving the signal-to-noise ratio in NMR devices. This project has been presented together with CEA in a granting scheme called “pamoja” that involved the NRF
The project I-UMEME funded under the ADESFA grant scheme, is an initiative aimed at disseminating information to empower Kenyan citizens in the context of the challenging electrical industry landscape within the African region. The electricity that is one of the main factors of development and integration needs to comply with rules that can not be accepted without a widespread education in electrical safety. The Project so far has reached more than 300 candidates, 80 certified so far.
The project KSK2 is an industrial project with the majors of LPG distribution in Kenya. It discusses the significance of preventing fire accidents in both residential and industrial settings that may arise from informal LPG refuelling. The originality of the approach proposed by the Unit is based on the fact that magnetic fields can be engineered together with a valve whose solenoid actuator in order to demonstrate the hardware lock-key mechanism for LPG safety in Kenya.
