Correct option is (d) 1, 2, 3, 4 and 5
Magnetite particles can act as pollutants and led to neurodegenerative problems. Magnetic particles can penetrate and damage the blood-brain-barrier and led to the early development of Alzheimer’s disease.
Whenever any magnetic component is used in appliances, they generate magnetic flux which produces magnetic particles.
Option 1 is correct. The automotive industry uses ceramic or ferrite magnets to make vehicles safer. One of the most impressive uses is in the Anti-lock Braking System (ABS) of vehicles. These use of magnets in motor vehicles can generate magnetic particles.
Option 2 is correct. Engines of motor vehicles can generate magnetic particles as they use high powered magnets which generate magnetic flux.
Option 3 is correct. In Microwave, a magnetic stirrer is used which can generate magnetic particles.
Option 4 is correct. Power Plants releases metal content along with ash. Use of coal in power plants is a major source of combustion-associated magnetite fine particles.
Option 5 is correct. Telephone line produces low frequency, low energy electromagnetic field which are the potential source of magnetite particles.
