= = = MICROWAVES = * How Micro-ovens use Electromagnetic Radiation?

A micro-oven is a device that uses electromagnetic radiation to cook food. Electromagnetic waves contain electric and magnetic fields. An electric field pushes or pulls other particles, a magnetic field pulls some metals towards it. All micro-ovens have a mechanical box which fires rad﻿iation at a fan which then scatters the particles, which are then absorbed by the food warming it up. In some cases radiation can leak out of microwaves but the radiation has not been proven to be harmful but large douses cause cancer. Micro-ovens use energy on the electromagnetic spectrum called microwaves. MIcrowaves are radio waves with the shortest wavelengths and the highest frequencies. Microwaves are not only used in micro ovens they are used in radars and phones.

How do Microwaves Effect Humans A Micro-ovens have many draw backs for example it is highly unsafe to put water in a micro-oven because it is super heated beyond it's boiling point once disturbed it can burst, causing severe burns this is all caused by electromagnetic radiation. Micro-ovens a ﻿ re dangerous in some cases, they can release electromagnetic radiation which has not been proved harmful though in large douses it causes cancer. Metals reflect electromagnetic which causes them to heat up, when a human touches it they can get severe burns or worse. Micro-ovens don't cook food evenly when cooking raw bits of it maybe cold which could leave bacteria. Micro-ovens can alter the properties of food they can increase some parts which many not be healthy and decrease nutrition turning food poisonous this happens in small douses though the food still may affect your health cooking with micro-ovens is not recommended.
