Magnets Physics LibreTexts
There are two type of magnets—ferromagnets that can sustain a permanent magnetic field and electromagnets produced by the flow of current as illustrated in the regions within the material called magnetic domainsact like small bar magnets Within domains the poles of individual atoms are aligned and each atom acts like a tiny bar
Custom Electromagnets & Coils Stangenes
Small Circular electromagnets are ideally suited for automated parts handling and packaging operations These durable magnets are easily controlled by 12 or 24 volt power supplies and have none of the maintenance noise or air pressure requirements of vacuum cups or grippers Electromagnets Lift magnets flex rare earth tools bar
