Magnetic Lines of Force Demo Set, 3D Magnetic Field Demonstrator

This is fun to have on your working table :)

This really is a good quality set. The 3D cube is unique and I can't wait to use it during our upcoming lesson on magnetic forces. The magnets are good quality, too.

This is as cool as I have seen. Iron particles randomly float in the clear fluid. Insert the magnet and the particles line up in 3 dimensions. I had prepped the kids on what to expect, but there were ahhhh's and ohhhh's when they lined up. They could easily see the effect. Without the clear fluid, it is really hard to demonstrate because the iron particles clump, bunch and stop moving. This is much better!!!

Great tool for teaching magnetic fields. Ideal for third or fourth grade. One caution: The cube and flat containers are filled with gel. If the small plug is dislodged, then the gel leaks out and makes a mess. I now handle the cube myself, as opposed to letting students play freely with it. Overall, a great visual aid.

I contacted the seller regarding the cube leaking and I got no response. Its very bad quality. disappointingly I wasted a lot of money

This is a very cool magnetic field viewer! We tried to make them in my middle school science class, but we couldn’t get close to this awesome viewer. My advice is to jiggle it he viewer back and forth instead of up and down to see the field lines most clearly. Great product!
