High-Strength Magnetizer |
An ideal device for magnets that have become demagnetized during use or for magnetizing soft iron of steel rods, it has two 2.5cm x 2.5cm holes, one polarized North and the other South.
The holes are large enough to accept almost any bar or horseshoe magnet. Bar magnets must be magnetized in pairs, connected with a soft iron block to complete the circuit.
Complete with on-off and magnetizing switches, a pilot light and a three-prong plug for operation on 115 VAC.
Size: 13.5cm x 8cm x 8.5cm high.

- Tuesday, April 03, 2012 Absolutly Necessary Reviewed By: Jim (Gainesville, Florida) If you are planning to do student activities using bar and/or horseshoe magnets, a magnetizer is a necessity. Magnets typically lose there strength during stored. The magnetizer is used to re-magnetize magnets easily and quickly. Be sure to check with pole of the magnet is north the first time you use the apparatus. An alternative is to get a screw driver magnetizer at a building supply store.
