LOWER SCHOOL
The Motor Effect is a very basic one. Look at a setting to the class, and decide which way the wire will move - and then click ' ON' to check.
How about this DC motor? Very nice work, Mr.Fendt! And how about this Generator with the graph of voltage out, ability to pause, and change frequency of rotation. You can remove the field, current, and force, directions to start with.
This is a basic transformer. You can change the number of coils, and it shows them on the core, and the amplitudes of the AC in and out change accordingly. And here is a much more sophisticated transformer, showing the magnetic field changing in the ring iron core.
UPPER SCHOOL
And here is you placing an electron somewhere near a proton, without, or with, initial velocity, and seeing its subsequent motion.
Dull simulation of capacitor charging, but you can change C and R and the charging graph changes immediately, which is helpful. Capacitor charging: This shows the supply voltage, Vc, and Vr, as columns that rise and fall, and shows the electron flow as yellow dots going around. Typically nice work by Professor Hwang in Taiwan.
This shows the resultant electrostatic potential around point charges very effectively; you can change the position and value of the charges
Charges, test charges, forces etc. Very nicely done
This shows the electric field lines around two charges; you can change the charges' positions and values.
Two charges, you click on a point, and it displays the electric field. Also shows the whole field as a collection of little vectors. Nice stuff!
This plots the resultant magnetic fields produced by currents. You can add more wires in.
This shows magnetic deflection of + and - charges in B (very basic). This is a document on magnetic deflection of charged particles, with pictures of the Aurora, equations, and the Hall effect.
