Electron Beam Deflection
Crookes tube is used to demonstrate magnetic and electrostatic deflection of an electron beam.

Magnetic Field About Wire
2 or 4 compasses are used to show the magnetic field generated by current in a wire.

Magnetic Field of Parallel Currents
Demonstrates magnetic attraction or repulsion of parallel currents.

Ampere Force
Force on a current-carrying wire in a magnetic field.

Faraday’s Law — Electromagnetic Induction
A scope is used to show the effect of a magnet being dropped through a coil

Induction Coils
Magnetic properties of a current-carrying coil, energy stored in a magnetic field, and mutual inductance can be demonstrated.

RL Circuit
Shows how an RL circuit responds to positive and negative square pulses.

Low-Pass and Hi-Pass Filters
This demo shows how rearranging components in RL/RC circuits can create low-pass or hi-pass filters.

Lenz’s Law – Lamp in Series with Inductance
Full brightness of a bulb in series with a large inductance is delayed for about one second in comparison to the bulb in a parallel circuit. If the iron core is removed from the coils, no delay is observed.

Lenz’s Law — Wonder Tubes
Magnet/non-magnet cylinders dropped simultaneously into aluminum tubes fall at different speeds.

Lenz’s Law — Jumping Ring
A coil with an iron core and two aluminum rings is used to demonstrate electromagnetic induction and Lenz’s Law.

Eddy Current Pendulum
Solid, flat, pendulum bob is slowed when it passes between magnetic poles. Bob containing slits oscillates freely.

Transformer
Coils with different number of turns allow the instructor to set up several step-down and step-up circuits.

Motor-Generator
A simple, large model can be used to generate current or to work as an electric motor.

Bicycle Generator
A bicycle with gears attached to an electric generator powers 3 headlights that can be turned on successively.

RLC Resonance
Parallel and series RLC circuits of variable resonance frequencies are available.

Jacob’s Ladder
Electric arcs continuously rise between two vertical conducting bars.

Tesla Coil
Homemade 1.2 million Volt Tesla coil generates long lightning-like sparks.

Mini Tesla Coil
Portable Tesla coil generates lightning-like sparks.

Electron Velocity Selector; Finding e/m Ratio
Motion of electrons in uniform electric and magnetic fields (and their combination) is demonstrated with a specially designed electron tube placed between Helmholtz coils.

Moving Electric Charge in a Magnetic Field. Lorentz Force.
Three demonstration are available. Spiralling electrons, Determination of e/m ratio, and Van Allen radiation belts.
