Magnetic Field For A Straight Conductor And Amperes Law
Concepts to remember for the “Magnetic Field for a Straight Conductor and Ampere’s Law”:
 Magnetic Field:

A region around a currentcarrying conductor or a moving charged particle where its influence can be felt. (Concept: Magnetic Field Region)

Represented by magnetic field lines showing direction and strength. (Concept: Magnetic Field Lines)

Strength directly proportional to current flowing through the conductor. (Concept: Current and Field Relationship)

Forms concentric circles around a straight conductor. (Concept: Magnetic Field Shape)

Direction given by the righthand thumb rule. (Concept: Righthand Thumb Rule)
 Ampere’s Law:

Relates magnetic field around currentcarrying conductor to current. (Concept: Ampere’s Law Overview)

Line integral of magnetic field around closed loop equals total current. (Concept: Line Integral and Total Current)

Can be used to calculate magnetic fields for various configurations. (Concept: Ampere’s Law Application)

Inside a solenoid, magnetic field is uniform and proportional to turns per unit length and current. (Concept: Magnetic Field in Solenoid)
