    Magnetic Induction

    Measure the strength and direction of the magnetic field at different locations in a laboratory. Compare the strength of the induced magnetic field to Earth's magnetic field. The direction and magnitude of the inducting current can be adjusted.

    Circuits

    Build electrical circuits using batteries, light bulbs, resistors, fuses, wires, and a switch. An ammeter, a voltmeter and an ohmmeter are available for measuring current, voltage and resistance throughout the circuit. The voltage of the battery and the precision of the meters can be adjusted. Multiple circuits can be built for comparison.

    Advanced Circuits

    Build compound circuits with series and parallel elements. Calculate voltages, resistance, and current across each component using Ohm's law and the equivalent resistance equation. Check your answers using a voltmeter, ammeter, and ohmmeter. Learn the function of fuses as a safety device.

    Photoelectric Effect

    Shoot a beam of light at a metal plate in a virtual lab and observe the effect on surface electrons. The type of metal as well as the frequency and intensity of the light can be adjusted. An electric field can be created to resist the electrons and measure their initial energies.

    Household Energy Usage

    Explore the energy used by many household appliances, such as television sets, hair dryers, lights, computers, etc. Make estimates for how long each item is used on a daily basis to get an estimate for the total power consumed during a day, a week, a month, and a year, and how that relates to consumer costs and environmental impact.

    Coulomb Force (Static)

    Drag two charged particles around and observe the Coulomb force between them as their positions change. The charge of each object can be adjusted, and the force is displayed both numerically and with vectors as the distance between the objects is altered.

    Pith Ball Lab

    Pith balls with positive, negative, or no electrical charge are suspended from strings. The charge and mass of the pith balls can be adjusted, along with the length of the string, which will cause the pith balls to change position. Distances can be measured as variables are adjusted, and the forces (Coulomb and gravitational) acting on the balls can be displayed.
