Magnetic Field
When you have a magnet, the magnetic field is created by putting test magnets which are compasses and mapping which direction they point
Earth’s Magnetic Field
Magnetic Field Direction
Field Conventions
Because, pages are 2D, we need a convention to help us conceptualize 3D
Right Hand Rule (Wire)
Thumb in direction of Conventional Current
Fingers is direction of magnetic field
Magnetic Polarity
To determine which side of the magnet is positive(North) and which is negative(South).
Right Hand Rule (Solenoid)
Thumb in direction of magnetic north
Fingers in direction of Conventional Current
