MAP MAGNETIC FIELD OF A ROOM
Learners map the magnetic field of a room (classroom or room at home -- recommend kitchen) at two or more heights. They create a coordinate grid within the room and make a relatively accurate map of the room to super impose the...
Curated OER
Exploring Magnetic Fields
Students develop the concept that magnets attract and repel items and exert a magnetic field that can vary in strength.

The Magnetic Field in a Current Carrying Coil
Students explore the relationship between a current in a coil and the magnetic field. In this physics activity students complete a lab activity using a magnet and batteries.
Curated OER
Invisible Investigations
Students simulate how charged particles move in a particle detector. In this physics instructional activity, students observe how iron filings behave when magnetic marbles are passed underneath them. They record and draw their observations.

Exploring Magnetism
Twelfth graders experiment with magnets in order to visualize that magnets have a north and south pole, some materials can be magnetized, and magnetization occurs because of the magnetic moments of individual molecules in matter.
Curated OER
Map Field of Current
Students determine that moving charges create a magnetic field. They discover that the speed and direction of motion, the amount of charge, and the deflection angle observed are closely linked. A voltmeter, pendulum, and a constructed...

Magnetism in Action
Third graders experiment with magnetic force and magnetic fields. They examine how magnetic forces can act through a distance.
Curated OER
Magnetic Fields and Bermuda Triangles
Students use a compass to determine the direction of a magnetic field at any point in space. They explain how two magnetic fields combine, then predict the location of areas where two fields can cancel each other to leave no resultant...
