### Radio Waves and the Lorentz Force?

Why have you put V as the velocity of the wave? You're misunderstanding what the right hand rule represents. The right hand rule, is a tool that is used to visually represent the cross product. The ...

### UV & IR radiation are mostly absorbed by water. Our eyes are predominantly water. If our eyes were made of another liquid, could we see slight UV/IR?

No. Over distances of order $1cm$ the absorption by water of near IR varies from about 1/1000 nearest the visible spectrum to near complete absorption at the low frequency end of near IR. For near UV ...

### Apparent instantaneous EM propagation paradox in two concentric solenoids

If you think there's really a paradox, then in order to resolve it, you should ask yourself which assumptions are definitely true, so you can reconsider any remaining assumptions by process of ...

### Apparent instantaneous EM propagation paradox in two concentric solenoids

If you are careful about all the delays, you will not find a paradox. For example, you strongly energize a long solenoid by applying a voltage to the ends of the wires. Perhaps you close a switch. ...

### Confusion in the showing EM wave exist from Maxwell equation

First of all, a general solution of a system of inhomogeneous linear equations (such the Maxwell equations with sources) can be always decomposed into a particular solution of the inhomogeneous ...

### How to reduce magnetic field between two magnetic shield sheets (silicon steel sheets)?

The best currently material for magnetostatic shielding of strong magnetic fields (high saturation value needed) is Giron: Mu-metal material although it has a better magnetic permeability has however ...

### How is light as electromagnetic waves produced?

Light is always produced by excited electrons dropping back to a lower energy state and releasing photons. The excitation of the electrons can be caused by other electromagnetic waves or electric ...
