Electromagnets from BuyMagnets.com provide an efficient, economical solution for handling and holding ferrous parts. BuyMagnets.com stocks many different shapes and sizes of electromagnets which are suitable for use in a wide variety of manual and automated applications. By utilizing a combination of electricity and magnetism, electromagnets excel at attracting and holding ferrous materials. Because an electromagnet’s current—and magnetic field—can be switched on and off, electromagnets have unique utility and advantages. Namely, electromagnets are ideal for picking up items at one location, transporting them, and then releasing them at a destination. Electromagnets increase production and facilitate automation. Note: All electromagnets require a proper supply in order to be operated properly.

FAQs

Electromagnets are a combination of electricity and magnetism. In an electromagnet, the magnetic field is produced by an electric current and disappears when the magnet is turned off. Through controlled use of electricity, the electromagnet can attract and hold heavy iron, scrap steel and other ferrous materials. The primary benefit of an electromagnet over a standard magnet is that the strength can be controlled. Our line of electromagnets will safely pick-up and move your material.

A power supply is required in order to properly operate an electromagnet, as electromagnets must be able to release ferrous objects as readily as they attract and hold them. Release is the function of the power supply—not the magnet.

Power supplies render a reverse current that ensures positive release of even those alloy steels that retain induced magnetism extremely well. All Bunting Power Supplies are designed to provide D.C. power for industrial electromagnets.

BPS3 Power Supplies are ideal for robotics or “pick and place” applications.

Electromagnets require little maintenance, and can be utilized in many different manual and automated applications. Electromagnets are frequently used to increase production and facilitate automation within various facilities. They are well-suited for applications where materials must be picked up at one location, held tightly while being transported, and then released at a destination.

Yes! The ability to switch an electromagnet’s current on and off has several advantages. One advantage is that when an electromagnet is not in use, it may be powered off for safe, risk free transfer. If handing a permanent magnet, the magnetic field will remain present, and could result in inconveniences or injury if the permanent magnet is allowed to be attracted to unwanted items when being transported. The ability to switch an electromagnet’s current on and off is what enables the unique portative feature of electromagnets. When the electromagnet’s magnetic field is turned on, it can pick up an item such as a heavy metal sheet and safely hold it while the item is traveling across a warehouse, for example. Then, once the item reaches its destination, the electromagnet can be turned off, allowing for safe release of the item.

An electromagnet’s main benefit compared to a standard, or permanent magnet, is that the strength of an electromagnet can be controlled. Because an electromagnet runs on electricity, its strength can be adjusted at any time based on how much electric current is allowed to flow through it. This is the greatest advantage of electromagnets, but also their greatest disadvantage, as electromagnets must have a constant flow of electrical current in order to maintain their magnetic field.

Electromagnets work by utilizing a combination of electricity and magnetism. In an electromagnet, the magnetic field is produced by an electric current, which then disappears when the magnet is turned off. Through controlled use of electricity, an electromagnet is capable of attracting and holding ferrous materials such as heavy iron, scrap steel, and more.
