AI Thread Summary
Electricity and magnetism are interconnected phenomena unified under the theory of electromagnetism, primarily described by Maxwell's equations. A changing electric field generates a magnetic field, while a changing magnetic field induces an electric field. This relationship is further clarified by Einstein's Special Relativity, which demonstrates that electric and magnetic fields are perceived differently depending on the observer's motion. Essentially, magnetism is observed when an electric field is in motion relative to an observer, and vice versa. Understanding these concepts reveals how electricity and magnetism are fundamentally two aspects of the same underlying force.

Two sides of a same coin. But how??

You are perhaps confused by the title, isn't it?
Well let me tell you what the question is.

Electricity and Magnetism are said to be "two sides of a same coin". But can anybody help me understand the actual relation between electric and magnetic fields and that how does electromagnetic induction works?

In short, I want to know how were the two phenomena- Electricity and Magnetism, unified into a single theory called 'ELECTROMAGNETISM'

If I point to you the Maxwell Equations, would that be sufficient?

Zz.
 
Yes, Maxwell's equations will give you the answer. Unfortunately, you have to be able to UNDERSTAND Maxwell's equations to appreciate that. Short answer (in English) is that a changing electric field has an associated magnetic field and a changing magnetic field induces an electric field.
 
Add to that the insights of special relativity and you'll see that what one observer sees as an electric field will appear as a magnetic field to a moving observer. In relativity, electric and magnetic fields are interwoven.

Magnetism is what you see when the electric field is moving compared to you.
Induction is the other side of that coin- When magnetism is moving compared
to you, you also see an electric field.
 
The simplest practical explanation: A wire with an electrical current through it produces a magnetic field in the surrounding space.

It is worth mentioning maxwell's equations have that two sides of the same coin aspect, as well as predicting that light itself is a wave of electric and magnetic fields.

The ultimate unification comes from Einstein's Special Relativity, which shows how electric and magnetic fields are the same thing seen from different points of view.
 
Thread 'Is there a white hole inside every black hole?'
This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
