Ampere's Law

Every time we mention the current in circuit as Ampere and we wonder what the heck is ampere and where does the name come from? Well dummies!!! look at the picture above shown. That  Man name is André Marie Ampère. He is the one who discovered about the current that comes under his name. We should thank him because his discovery change the world,but he leave some equation and law to learn about the current. So dummies!! be ready with your Einstein brain!! Because we going to learn Ampere's Law.

Ampere's Law state that a current carrying conductor creates a magnetic field around it. The bigger the current, the stronger the magnetic field.

For example, when a conductor like wire carries current, it will create a magnetic field around the wire. Now if we send big amount of current, so there will be big size of magnetic field. (The magnetic field of wire will be Circular) This mean the size of the magnetic field is proportional to the amount of current flows through the wire. To determine how the magnetic field is create around the wire and also depend on the length of wire the Ampere's law equation will be :

 'B' stand for the magnetic field and L is for length. This both is proportional to µ₀ means the magnetic permeability is  4π × 10⁻⁷ H·m⁻¹ times by the current and divide by the area of circular magnetic field 2πr.  This formula is to determine the magnetic field of this straight  current carrying conductor.
