电脑辐射最大在键盘谣言（Computer radiation at the keyboard The rumor）

电脑辐射最大在键盘谣言（Computer radiation at the keyboard The rumor） Computer radiation at the keyboard? The rumor? Some netizens wrote that the computer radiation is the biggest in the keyboard, and there are specific Numbers: 1. Keyboard 1000V/m; 2. Mouse 450V/m; Screen 218V/m; 4. Mainframe 170V/m. These Numbers are very real, and they seem real and scientific. In fact, this is just netizens ignorance of the science. (1) make clear four units: electric field intensity, magnetic field intensity, magnetic induction intensity, and power density 1. Electric field intensity (E), whose unit is volt/meter, or V/m, the electric field intensity is used to describe the intensity of the space electric field. 2. Magnetic field intensity (H), whose unit is ampere/meter, also known as A/m, magnetic field intensity is used to describe the intensity of the space magnetic field. 3. Magnetic induction intensity (B), whose unit is tesla T, is a basic physical quantity, which should be specified in particular: Magnetic field intensity and magnetic induction intensity are both physical properties of magnetic fields, and the strength of magnetic field can be expressed in two ways: In the case of uniform magnetic media, the magnetic induction intensity B is used to represent the tesla T, which is a basic physical quantity when the magnetic field is included in the magnetic field. The magnetic field that is caused by the current or the motion charge alone (excluding the magnetic field generated by the magnetization of the dielectric) is represented by magnetic field intensity H, and its unit is A/m, which is an auxiliary physical quantity. Due to historical reasons, and the electric field intensity corresponding to describe the basic physical quantities of the magnetic field is known as magnetic induction intensity (not called magnetic field strength), and the other auxiliary materials are referred to as magnetic field, it is really a bit inconsistent actuality, easy to confuse. But theres no way t
