Electromagnets
Overview
Adams Magnetic Products offers a wide range of electromagnets designed for controlled holding power and on-command release. These electromagnets are suitable for various industrial and consumer applications, providing reliable and customizable solutions.
What are Electromagnets?
Electromagnets generate a magnetic field through the flow of electric current, which disappears when the current stops. They offer controlled holding power, attracting and holding ferrous materials with varying degrees of force and releasing them as needed.
Advantages
- Controlled Holding Power: Ability to control magnetic force with electrical current.
- On-Command Release: Easily release held materials when the current stops.
- Customizable: Available in various sizes, shapes, and current strengths to meet specific requirements.
Advantages
- Variety of Forms: Available in flat-faced round, rectangle, and bi-polar rectangle forms.
- Customizable Options: Different sizes, shapes, and current strengths.
- High Performance: Suitable for both manual and automated applications.
Applications
Electromagnets are used in:
- Electric bells
- Industrial lifting magnets
- Loudspeakers
- Magnetic locks
- Magnetic recording and data storage equipment
- Magnetic separation of materials
- Motors and generators
- Relays
Small Bi-Polar Electro Magnets - 12VDC (24 VDC 110 VDC Optional)
The magnetic field of bi-polar electromagnets has a greater "reach" than that of flat-faced electromagnets. Subsequently, they perform better than equivalent flat-face magnets when operating through an air gap or any type of non-magnetic material between the workpiece and the electromagnet. Bi-polars, due to their extended poles, are designed to handle round parts, parts with uneven surfaces, and odd shaped parts. Contoured, auxiliary pole shoes can be added for better contact with the workpiece.

Power Sources
Electromagnets require direct current power in order to generate a magnetic field. Typically the applied voltage is Direct Current (DC), but in some cases, Alternating Current (AC) can be used. Variable power sources and remote control are available. Smaller magnets can operate on 12 volts DC; larger magnets may require 115 or 220 VDC. A rectifier is required to release the electromagnet from the surface on which it is applied. The rectifier can be mounted on the magnet, and be operated by remote control.
Whether used in manual or automated handling of ferrous parts, they must release the work as readily as they attract and hold. Release is a function of the rectifier and not the magnet. Most rectifiers incorporate a provision for reverse current that ensures positive release of even those alloy steels which are magnetically retentive. Variable power and remote control are available.
Adams does not stock rectifiers but offers them through special order. Please inquire for your requirements. Another method of obtaining direct current for magnet operation is through use of 12-volt batteries
