1. Magnetic Field Permanent magnet Charges in motion
Electrons spinning about their own axis in a particular alignment
Charges in motion
Electric current
Represent by closed loops
Flux lines
Magnetic polarity
North, South
ECE 201 Circuit Theory I

2. Right-Hand Rule
Grasp conductor with right hand, thumb pointing in the direction of conventional current flow
Fingers curl in the direction of magnetic field (lines of flux)
ECE 201 Circuit Theory I

3. Through a Coil of Wire
Grasp the coil with the right hand, fingers curled in the direction of current
Thumb points in the direction of the magnetic field
ECE 201 Circuit Theory I

4. For a Permanent Magnet
Magnetic field direction is OUT from the NORTH pole and IN to the SOUTH Pole
