Power Supplies
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.
Note: Total wattage of all magnets powered by a single Bunting Power Supply must not exceed the wattage rating of the Power Supply. For example, one to five 3-watt magnets can be used with a 15-watt Power Supply.

Rectangular flat-faced electromagnets are available from BuyMagnets.com in six different standard varieties. Width options range from 1.5” to 4.” Length options range from 1.5” to 8.” Height options range from 1.25” to 2.5.” The holding force of these electromagnets ranges from 100lbs to 2000lbs. Upon request, we are able to provide our customers with special sizes.
It is best to use rectangular flat-faced electromagnets with surfaces that are flat, smooth, and dry. When the entire face of the rectangular flat-faced electromagnet is allowed to come into direct contact with the product that is being handled, it is able to achieve its maximum holding force. These rectangular flat-faced electromagnets are designed with a center magnetic pole, and use their outer casing as an opposite pole. This concentrates the magnetic force at the center of the magnet, and results in superior holding power.
All rectangular flat-faced electromagnets from BuyMagnets.com are durable and built to last. Our electromagnets provide a simple, efficient alternative to mechanical holding devices and facilitate automation of tasks within your facility. Electromagnets do not produce any waste by-product, and do not have any moving parts, springs, or valves that run the risk of wearing out. A low-maintenance electromagnet allows you to easily, quickly, and safely move large and heavy ferrous materials, such as large metal sheets, throughout your facility with ease.
All electromagnets from BuyMagnets.com are 100% duty cycle.

Round flat-faced electromagnets are available in thirteen standard options from BuyMagnets.com. Diameter options range from 0.50” to 6.” Height options range from 0.75” to 3.” The holding force of these electromagnets ranges from 4lbs to 1000lbs. If you have a special request, we also have the ability to supply you with special custom sizes.
For best results, it is recommended to use round flat-faced electromagnets on surfaces that are smooth, flat, and dry. A round flat-faced magnet is able to achieve its maximum holding force when the entire face of the magnet is permitted to come into direct contact with the product being handled. Round flat-faced electromagnets are designed with a center magnetic pole, and use their outer casing as an opposite pole. This design is able to concentrate magnetic force at the center of the magnet, and the result is superior holding power.
Every round flat-faced electromagnet from BuyMagnets.com is durable and built to last. Round flat-faced electromagnets are able to facilitate automation of tasks within your facility and provide an alternative to mechanical holding devices that is simple, safe, and efficient. Electromagnets do not have any moving parts, such as springs or valves, that are at risk of running out. Additionally, electromagnets do not produce any waste by-product. Low-maintenance electromagnets facilitate easy transfer of large and heavy ferrous materials.

Electromagnets and Power Supplies
Strong Electromagnets - 100% Duty Cycle
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. Choose from strong, small rectangular electromagnets and round electromagnets. By utilizing a combination of electricity and magnetism, electromagnets excel at 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: Electromagnets operate as holding magnets when they come in direct contact with ferrous materials, they will not attract or repel ferrous materials when placed at a distance. All electromagnets require a proper supply in order to be operated properly.

FAQs
What Are the Benefits of Electromagnets?
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.
Why Are Power Supplies Needed?
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.
Consult for technical recommendations.
What Are Electromagnets Used For?
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.
Can Electro Power Be Controlled?
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.
How Are Electros Different From Other Magnets?
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.
How Do Electromagnets Work?
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.
