Circuits and Magnetic Fields
Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is created...
Teach Engineering
Electricity and Magnetic Fields
Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.
Teach Engineering
Drawing Magnetic Fields
Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...
Teach Engineering
Magnetic or Not?
The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform tests to...
Teach Engineering
Visualizing Magnetic Field Lines
Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil.
Teach Engineering
Magnetic Resonance Imaging
The capstone lesson in a 14-part series focuses on the basics of magnetic resonance imaging and the hardware of the machines. Pupils use this information and the material learned throughout the unit to develop a presentation on safety...
Teach Engineering
Induced EMF in a Coil Wire
Small groups investigate the interaction between a coil of wire and a magnet to create an electromagnetic field and observe the voltage they create. Through further interactions, they realize a conductor can be charged from the...

Slinkies as Solenoids
What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see the...
Teach Engineering
Biot-Savart Law
Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...
Teach Engineering
Both Fields at Once?
An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...
Teach Engineering
May the Magnetic Force Be with You
Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor, learners...
Teach Engineering
Force on a Current Carrying Wire
What do electrical currents have to do with an MRI? Using a simple wire setup and a magnet, class members explore forces used in an MRI by investigating the magnetic force acting on a wire carrying a current.
