Test out different sail designs without going near water! The Mag Sailer provides a way to design and test the characteristics of sails while utilizing your maglev track. Make this vehicle with one or two sails, make different sail shapes, center them or put one or two at the front or back – choose one of many variables to test. Then, blow them down the track using a consistent source such as a small fan or hair dryer.
Includes magnets, chassis, two dowels, self-adhesive tabs, and O-rings needed for one sail car. Requires a Maglev Track or Maglev II Track, fan or hair dryer, HD Bond II, hole punch, sail material (copy or construction paper), and scissors, sold separately.
Note: The Mag Sailer cannot be electrified; it can only be used on gravity tracks.
This handy tool for identifying the polarity of a magnet is ideal when putting together a Maglev II Track, maglev vehicle, and other magnetic activities.
Magnetic levitation comes down to Earth – and the desktop – with this small and affordable maglev track and car. Students can assemble the track and run the included basic car – or use other gravity-operated vehicles such as the Levitator Maglev Kit or Mag Sailer that also work on the Maglev II Track.
Constructed of sturdy Britefold paperboard that is die cut, the track is 18" long and 2-9/16" wide. Metal brads and glue dots make an easy assembly of the track and car, so no cutting is required.
This 8" plastic-coated magnet is ideal for young students. Lifts up to 4 pounds.
More than 150 years before we all carried cell phones, Morse code enabled people to communicate over long distances by using electrical currents. This kit uses a lightbulb to signal dots and dashes so students will see the currents. Requires a D battery, sold separately.
Do electromagnetic propulsion systems and braking systems like those used on roller coasters interest your students? If so, give them a close-up look at what makes it possible: eddy currents. The magnetic track connects to the battery to create an eddy current that will roll a metal tube down it.
Some assembly needed. Requires a 6 V lantern battery, sold separately. Caution: No other power source should be used.
With magnetic levitation, objects can be levitated, or held floating in midair, by the force of magnetism. In this video, Dr. Zoon illustrates some of the scientific principles behind magnetic levitation, and he goes step-by-step through the process of building and testing a maglev vehicle.
What do radios, microwave ovens, and X-ray machines have in common? They all use different forms of electromagnetic energy. With this video, discover how cosmic rays from space and visible light are part of the family of energy waves known as the electromagnetic spectrum.
Part of the Energy in Action Video Series. Teacher’s guide included.
Understanding how motors work lays a solid foundation for understanding generators and numerous electrical devices. Now, this self-contained and simple kit makes demonstrating permanent and electromagnetic motors an easy operation to run.
The included guide discusses electromagnetism, DC motors, generators, electricity facts, and assembly instructions.
Which uses more electricity: a hair dryer or a stereo? Now you can find out with the Watts Up? Pro, an electrical watt meter that instantly calculates the energy use of any appliance. It also has memory and the ability to download its data to a PC.
Simply plug any 120-volt AC device into Watts Up? Pro. The wattage being used is instantaneously displayed on the meter and stored in memory. One thousand data points are stored, starting with a sampling rate resolution of one minute. The sample rate resolution increases over time so years of usage can be accurately recorded. The included serial cable and software program allow the data to be quickly downloaded to a PC for creating usage charts. Data can also be exported in comma-delimited format to a spreadsheet for analysis and comparisons.
Watts Up? Pro displays and stores 16 key measurements: cost, wattage, cumulative power, time, voltage, current, monthly average cost, maximum and minimum voltage, maximum and minimum current, maximum and minimum wattage, power factor, duty cycle, and power cycle.
This strip has the north and south polarity on opposite sides, which makes it useful for levitation demonstrations. It is also useful for many different projects and applications dealing with physics and transportation. Supersaturated for greater holding power. 5' x 1/2", 1/4" thick.
The battle over currents between Edison and Westinghouse may be long over, but understanding how both AC and DC currents work is still a vital part of understanding electricity and how we use it. This hand generator demonstrates how each current is produced.
With banana plugs to easily switch between currents, the AC/DC Generator Demo Kit also features a clear base for easy viewing of the connections. Includes an activity guide.
