Explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet! Can you make it a stronger magnet? Can you make the magnetic field reverse?
Investigate the strength of magnetic fields at different distances. Build a series of electromagnets with different coil lengths and/or different core materials and investigate the magnetic fields produced by each.
You can either take your ruler measurement of the distance between your two points and place that on the scale to determine real distance, or you can use scratch paper and go from the scale to the map.
How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance.
Make all sorts of things move with magnets. Use magnets to power motors, levitation, and acceleration. Or apply them to life science, where their attraction qualities help model DNA copying, cleaning up oil spills, or separating mixtures.
25 kwi 2017 · Attraction and repulsion projects are good for fourth graders first beginning to explore magnetism. A magnet has two poles (north and south) and magnets either attract or repulse each other depending on the orientation of the poles.
Grade Level: 4th – 6th; Type: Physics. Objective: This science project demonstrates how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.
