How can you quickly slow down a spinning wheel without touching it? With a magnet of course! A changing magnetic field generates temporary electric current loops in conducting metals. These current loops generate their own magnetic field, even if the... AP5636 - $140.65

Clearly demonstrate Faraday's law! Pass a magnet through a wire coil connected to an ammeter and the ammeter needle deflects-an electric current is produced. When the magnet stops moving, the needle returns to zero. Which of the three coils generates... AP5637 - $64.45

What can lift 100 times its own weight? Answer: This electromagnet! Lift up to 200 pounds using one 1.5 V D-cell battery! Students will remember this dramatic demonstration for years. The precision machined contact surfaces make this electromagnet... AP5728 - $29.90

Use this economical kit to teach all the basics of electromagnetism. Students can build a bar magnet or a U-shaped electromagnet. Measure the polarity and magnitude of electromagnetic forces. The kit includes two coils on plastic spools, a U-shape... AP6758 - $69.00

Clearly demonstrate Faraday's law! Pass a magnet through a wire coil connected to an ammeter and the ammeter needle deflects-an electric current is produced. When the magnet stops moving, the needle returns to zero. Which of the three coils generates... AP6271 - $88.25

A powerful series of lab activities to help your students learn the basics of electromagnetism. • First, students will explore magnetic fields created by electric currents traveling through wires. • Then students build an electromagnet and experiment... AP4540 - $14.20

Demonstrate the conversion of electrical energy to mechanical energy using this small electric motor with attached wheel and axle. Motor runs on regular or homemade batteries. Set includes motor, attached wheel and axle, and a weight (for lifting).... AP4629 - $69.35

Seeing “inside” an electric motor as it operates is a real attention-getter. All the parts are clearly visible so you can show each component of a motor or generator in operation. This remarkable teaching tool comes with instructions for performing... AP4630 - $58.35

• Electromagnetic Induction • Faraday's Law of Induction
• Lenz's Law
• Step-up and step-down transformers
• Induced current • Induction of current vs. induction of voltage
AP4635 - $9.95

There is no better way to understand how an electric motor works than to build one yourself! Students first begin by constructing their own motor parts such as the armature, commutator, and brushes. They then assemble the motor parts, hook up the power,... AP6263 - $31.25

In minutes, students can build a simple spinning motor using just a magnet, copper wire and a 9-V battery. Once they learn what makes the motor run, they can experiment with various designs to see who can construct the fastest-spinning motor! Excellent... AP9230 - $61.65

Investigate magnetic fields produced by an electric current. Students observe as a current carrying coiled wire produces a magnetic field perpendicular to the direction of the current. Students learn that the strength of the magnetic field varies with... AP6585 - $65.40

Convert mechanical energy into electricity with this rugged power plant! With a turn of the crank, students can conduct dozens of hands-on experiments to study electromagnetism, polarity, simple circuits, resistance, and mechanical work. Nylon-plastic... AP6588 - $67.05

Demonstrate how a current-carrying wire in a magnetic field will be acted on by a force. Verify the Right-Hand Rule by changing the direction of the current and observing a corresponding change in the direction of the force. Then, generate alternating... AP6586 - $707.80

Arouse your students' interest in electricity with this all-inclusive electricity kit. An assortment of unique equipment is provided for students to conduct over 20 hands-on experiments to discover the properties of electricity and magnetism. Students... AP6590 - $52.80

Turn the electricity produced by the Genecon hand generator into a powerful electromagnet! Students experiment with the Genecon hand generator and determine how much physical effort they must exert in order to pick up metallic objects. Next, they can... AP6761 - $26.95

Electrifying! Transform a simple lightbulb into a glowing, sparking plasma globe while teaching students about important topics such as electric current, electron energy levels, and photon emission. Simply screw a clear lightbulb into the Marekizer... AP6911 - $36.25

Shocking! Create a safe lightning storm in the comfort of your classroom. The electrically charged base creates colorful arcs across the gas inside the globe. Watch as the electric arcs migrate towards a hand placed on the globe. Use it to teach about... AP7320 - $55.55

Shake and light up your classroom! Engage your students by building a flashlight that doesn’t need batteries—it harnesses and stores the power of a handshake. Students see an unforgettable, real-world application of Faraday’s law of magnetic induction....
