Percentage Electrical Conductivity of Material

In this table we will discuss about the conductivity of materials. A-lot of people on google are searching " Silver is more conductive than gold ? " | " Conductivity of copper vs conductivity of silver ?" | " Aluminium Vs Copper in wires " etc.

All your answers can be found using this chart.
The Top Conductive Materials are arranged in their descending order.

Name of Material	Percentage of Conductivity
Silver	104-105
Copper	98-100
Gold	65-70
Aluminium	56-61
Nickel	20-22
Zinc	27
Brass	28
Iron	17
Tin	15
Phosphor Bronze	15
Lead	7
Nickel Aluminum Bronze	7
Steel	3 -15

So We can see from this table that Silver is the most conductive material. 

Flemings Right Hand Rule with diagram

To Remember and understand Fleming's Right Hand Rule Always Remember a simple Phrase - FATHER MOTHER CHILD , how is this helpful ?

Well ,F from father will represent F for Force 

M from Mother will represent M for Magnetic Field

C from Child will represent C for Current. 

So if we place our fingers like this :

That means Thumb , Index Finger and Middle finger all aligned at 90 degrees to each other. 

Then Thumb will represent Motion of Force , Index Finger will represent Direction of Magnetic Field and Middle finger will represent Direction of Current. All Perpendicular to each other.
