Why is electromagnetism important in today’s society?

Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.

How does electromagnetism affect our daily life?

Possible health effects Exposure to electric, magnetic and electromagnetic fields (EMF), if they are strong enough, can lead to short term health effects. Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves.

Does electromagnetism affect human body?

The main effect of radiofrequency electromagnetic fields is heating of body tissues. Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

What are the advantages and disadvantages of EM waves?

They are electromagnetic waves with wavelengths just shorter than those of visible light. Advantages: In small quantities they help your body produce vitamin D. Disadvantages: They can cause sunburn or even skin cancer if used in large quantities.

What are the advantages of EM waves?

The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi.

What are the dangers of EM waves?

Possible effects of EM Radiation exposure & Hazards of Electromagnetic Radiation

• Cataracts.
• Blisters on the skin.
• Sterility and microwave auditory effect, which is hearing buzzing or microwave pulses.

What are the 7 wavelengths?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

Which three types of waves can be harmful to life?

The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.

What are the 5 types of radiation?

Radiation

• electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
• particle radiation, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy)

Which frequencies are dangerous?

Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).

At what GHz is dangerous?

300 GHz
