Electromagnetism

Conductivity Water Tester

Lamp brightness is controlled by the conductivity of liquid in which the two electrodes are immersed. No exposed metal parts. More.

Metal Detector

This multi-sensing metal detector distinguishes between metal and non-metal objects, displaying readings using tone and LEDs to indicate intensity. Learn how magnetic fields can be used for industrial and recreational purposes. Features adjustme... More.

Oersted’s Law Apparatus

Study the relationship between magnetism and the magnetic effect of electric current flowing in a wire with this classic device. This 15 cm long permanent magnetic needle rotates freely inside an aluminum frame that allows current to flow over or under ... More.

Copper Voltameter

Used to measure electric current by weighing the negative electrode before and after electricity is provided. The change in weight is proportional to the amount of electricity provided. Experiment with electrolysis. Three thick copper plates with brass ... More.

Mass of Electron Apparatus

Ever wanted to measure the mass of an electron in your classroom? Now you can! The mass of an electron and the strength of the earth’s magnetic field can seem like giant abstractions that are impossible to prove, but not with this apparatus. Consi... More.

Electric Circuits and Electromagnetism Kit

An introductory kit provides students with materials to “breadboard” various electrical circuits such as series and parallel circuits; controlling circuits with switches; investigate conductors and insulators; make electromagnets; and sugges... More.

SciQuest® Electromagnetism and Current Electricity – Intermediate Level Multi-Group Kit

Kit Features: • Content presented compatible with all commercial texts • Sequential format of concept development, at three levels, facilitates the option for multiple use of the kit by classes at two or three different grade levels • Exc... More.

Electromagnet Experiment Set

The materials in this set allow students to determine how the strength of an electromagnet is affected by the number of turns in the coil, and by the nature of the material that occupies the space inside the coil. The set includes three pairs of coils, ... More.

Lenz’s Law Model

This great demonstration teaches Faraday’s Law of Induction as well as Lenz’s Law. Show how passing a magnet through the complete loop causes the device to move and why passing the same magnet through the split loop causes no movement. Grade... More.

SciQuest® Electromagnetism and Current Electricity Intermediate Kit and Set of 2 Teacher DVDs

Curriculum based! Follows standards! Specific concepts investigated relate to: magnetic fields around conductors, the “left hand rule” for determining direction of current flow and magnetic field in conductors, “closed” an... More.
