Magnet
Ring Demonstration Set
Dramatically show that magnetic poles repel each other by placing ring
magnets on a non-magnetic stand. The magnets float in the air, one
over the others, and spring back up when pushed down. The set
contains five ceramic ring magnets, each 32 x 18 x 6mm, magnetized
parallel to the axis. They are guided by an acrylic rod mounted on
a plastic base.
No. SD220-RG. Only $9.95 |

Magnetic
Needle on Stand
Great for studying magnetic phenomena such as the the operation of a
compass, testing of magnetic poles and finding the direction of electric
current. Consists of a magnetized steel needle about 150mm long
with brass bearing pivoted on a non-magnetic metal stand. The
north pole is marked in red. When not in use, the needle is
reverse and kept in the main for for safety.
No. SD220-ND. Only $11.95 |
