The Strong Hand Adjust-O Dual Switch Magnet is great for any fabricator shop or welder.
Just turn off the magnets and wipe them clean. This dual switch magnet is perfect for setting flat, angled, square and round stock. Everything remains securely in place, kept at angles up to 90 degrees. These powerful magnets deliver an extremely strong hold-down force. Rare Earth magnets are truly amazing and totally dependable. The magnetic squares on the Strong Hand Adjust-O Dual Switch Magnet securely hold pieces for welding. The Strong Hand Adjust-O Dual Switch Magnet from Welders Supply is a must-have tool. It not only saves time and money, it also helps reduce downtime due to workplace accidents and mishaps and makes it easier to produce higher quality work. Patented on/off switches (one on each magnet) make this a truly dependable and simple-to-use tool. It weighs only 2.7 pounds yet has a pull of a hundred pounds. You’ll really appreciate the strength, accuracy and durability of this excellent welding companion. The Strong Hand Adjust-O Dual Switch Magnet from Welders Supply is the extra hand you’ve always said you needed! It’s a powerful, heavy-duty magnet with two independent switches, making positioning easier and safer than ever.

and consume zero power whether magnetically holding or free to be moved around. Still, with a bit of ingenuity and lever mechanics, a magnetic holding fixture can be made that will release with the turn of knob. One downside is their magnetic field is not easily turned on and off at will. They can produce a very strong magnetic field with zero power input and very little mass or volume compared to an equivalent strength electromagnet. One of the nicest things about permanent magnets is their size.
More than one discharge may be necessary to obtain the strongest residual permanent magnetic field possible. The resulting high-current discharge creates a strong but rapidly decaying magnetic field in the permanent magnet, causing its magnetic domains to align with the external field. There are several different ways to "magnetize" permanent magnets, but one of the easier ways is to energize a large capacitor to several hundred volts potential and then connect it (quickly) across the magnetizing coil of the electromagnet. Then the current is increased until the desired field strength in the permanent magnet is produced. After forming to the desired dimensions, it is placed between the magnetic poles of a VERY strong electromagnet. No current means no magnetic field (except for a very small residual field) so, as mentioned, electromagnets are used in scrap yards to pick up and move ferrous materials around, dropping their "load" when the current is turned off.Ī permanent magnet, such as a neodymium or other rare-earth magnet, or even an Alnico permanent magnet, always starts out as an un-magnetized object. The magnetic field produced by an electromagnet is temporary, and its strength is determined by the current in the electromagnet: more current produces a stronger field.
