5H30. Force on Moving Charges
- 5H30.15 Bending Electron Beam An electron beam hitting a fluorescent screen in a tube is bent by a magnet.
- 5H30.20 E/M Tube Show the beam of the E/M tube in Helmholtz coils in a darkened room.
- 5H30.30 Rotating Plasma A plasma tube powered by an induction coil is placed over an electromagnet.
5H40. Force on Current in Wires
- 5H40.10 Parallel Wires Current can be passed parallel or antiparallel in long hanging wires to show attraction and repulsion.
- 5H40.11 Parallel Wires Rectangular loops of solid wire hang on pivots from two stands. Used together, demonstrate parallel wires.
- 5H40.30 Magnetic Force on a Wire A current passed through a wire in a horseshoe magnet will move one direction or the other depending on the current direction.
- 5H40.50 Barlow’s Wheel A potential is applied from the axle of a wheel to a pool of mercury at the rim while the wheel is between the poles of a magnet.
- 5H40.75 Dipolar Express An AA battery with magnets affixed to each end, racing around the inside of a coil of wire.
5H50. Torques on Coils
- 5H50.41 Floating Coil A vertical coil energized by a flashlight cell floats in a large pan and is attracted to a stationary magnet.
