Einstein-Podolsky-Rosen effect; EPR effect:
Assume the following quantum mechanical thought-experiment: Take a particle that is at rest and contain spin zero. It decays spontaneously in two fermions (spin 1/2 particles), which stream away into opposite directions at high speed. Because of the law of conservation of spin, we know that one is a spin +1/2 and the other is -1/2. Which one is which? According to quantum mechanics, neither takes on a specific state till it is observed (the wavefunction is collapsed).
The EPR effect revel that if one of the particles is detected, and then its spin is measured, then the other particle no matter where this is in the Universe immediately is forced to select as well and take on the role of the other particle. This demonstrated that certain kinds of quantum information instantaneously travel; not everything is restricted by the speed of light.
But, it can be demonstrated easily that this effect does not make faster-than-light communication or travel possible.

Displacement: - The modification in position of a body in a certain direction is known as displacement. It is a vector function and its unit in SI system is meter.

Electromagnetism: A temporary magnet formed by winding a coil of insulated copper wire around a piece of shift iron is known as electromagnet. When current is passed it behaves
It contains 35%- 90% nickels. Higher is the nickel content higher is the permeability and lower is the magnetic saturation of the alloy. MN, CO, and Mo can also be added in trace q
as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
