My Demo Videos:
Video of Shrinking a Coin with a Magnetic Field (induced, actually)
Video of a High Voltage Can Crusher (again, with induced current)
How powerful can magnets be? Check out this company's website. Scroll down to the super magnets and be amazed!!!
Or buy magnets here: supermagnetman
Compass and Magnetic Fields from Electricity (Applet) - click on the switch and see how the compass moves in the magnetic field.
Induced Emf within a Solenoid (Applet) - Like how we did in class. Unfortunately you can't switch the magnet's direction.
Lenz's Law (Applet) - Move a magnet into a wire coil. The blue shows the induced magnet field trying to oppose the bar magnet. Then you can see the induced current in the coil.
Induced Current when Area is Changed (Applet)
Charged Particle in a Magnetic Field (Applet) - watch the path.
How a Generator Works (Applet) - See how the maximum emf occurs when the coil breaks the field lines. If you slow it down, it's easier to see.
Generator 2 (Applet) - Not as easy to see, but notice the permanent magnets the rotor is moving inside.
How a Motor Works (Applet) - Notice the commutator and how it keeps the electromagnet always in the same direction.
Construction of a DC Motor - close to what we made in class.
How a Transformer Works (Applet) - You can change the primary voltage and the number of coils for both primary and secondary.
