Experiments with magnets and our surroundings

Twelve Fundamentals of Magnetism

In order to better understand magnets and electromagnets, there are 12 fundamental topics that one needs to know and understand. 
With these fundamentals under your belt, you will be better equipped to design magnetic circuits for whatever you are trying to accomplish.

They are:

1.    Conventions used for currents and fields
2.    Magnetic Flux, Wb
3.    Solenoid winding configuration
4.    Flux Density, B
5.    Magnetomotive Force, MMF
6.    Magnetic Field Intensity, H
7.    Hysteresis Curve (B-H Curve)  
8.    Permeability,
9.    Magnetic Domains and Saturation
10.  Generator Action
11.  Transformer Action
12.  Motor Action

I would suggest that you start at the top and work your way through since they build on each other.  Then, if you'd like to try your hand at designing a magnetic circuit, just click on this link:
