Oersted, electric current and magnetism
... Oersted imagined an electric current ‘struggling’ through a wire. As it flowed, this ‘conflict’ gave rise to heat and light, which radiated away from the wire. Might it not also result in a magnetic field, radiating away? Question: How would you draw magnetic field lines to represent Oersted’s idea? ...

Trapping and Manipulating Neutral Atoms with Electrostatic Fields
... would be limited by the achievable beam waist. This problem could be overcome by introducing switchable electric fields at each trap site that would be used to shift the atoms in and out of resonance with the light frequency. In contrast to the current experiments where the goal was to trap atoms wh ...

Make a Motor
... Motor #1 is a kind of homopolar motor, meaning that the polarity of the motor does not change (the positive and negative sides of the motor always stay the same). When you touch the wire from the top of the battery to the magnets below, electromagnetic force is created. That force runs parallel (th ...
