Magnet Type
          Unlike permanent magnets, electromagnets use electricity to generate a magnetic field. Additionally, the magnetic field of electromagnets can be turned on or off as needed.
   Your choices are...         
   Flat-faced Magnet       Flat-faced magnets are used when the entire face of the magnet is in direct contact with the surface, and the surface is smooth and flat. 
   Parallel Pole Magnet       Also called bi-polar electromagnets, parallel pole magnets have two widely spaced poles, which allow the magnetic field to have a greater reach. These magnets may be used when the magnet has only partial contact with the surface, to handle an irregular shape, or when it must work through an air gap. 
   Standard Lifting Magnet       Electromagnets intended to lift solid, compact material such as billets, steel plate, bars, forgings, etc. Standard units are not intended for handling scrap or small parts. 
   Suspension Magnet       Suspension magnets are powerful magnets for lifting heavy and/or odd shaped magnetic materials.  These magnets are often used in process manufacturing, material handling, or for scrap yard use. 
   Laboratory Electromagnet       Laboratory electromagnets are typically used in labs for research.  Common configurations are dipole, quadrupole, or sextupole electromagnets. 
   Permanent / Electromagnet Combination       The permanent / electromagnet combination provides for safely holding the load, even if power is accidentally removed from the magnet. 
   Other       Other unlisted, specialized, or proprietary configuration. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Strength
   Holding Force       The force the magnet is capable of holding under ideal conditions.  Conditions such as the size and shape of the parts, the surface conditions, motion, vibration, friction, holding angles, and machining forces will affect the holding force of the magnet and should be factored into the magnetic circuit design 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Magnetic Field       The strength, in gauss, of the magnetic field created by the magnet. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Energy Product, BHmax       Also known as the magnet strength or grade.  The point on the demagnetization curve where the product of B and H is a maximum and the volume of magnet material required to project a given energy into its surroundings is a minimum. It is measured in mega gauss-oersteds, MGOe. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Residual Induction, Br       A value of induction at the point at which the hysteresis loop crosses the B axis at zero magnetizing force. The Br represents the maximum magnetic flux density output of this material without an external magnetic field. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Coercive Force, Hc       The demagnetizing force, measured in oersteds, necessary to reduce observed induction, B to zero after the magnet has previously been brought to saturation. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Intrinsic Coercive Force, Hci       The intrinsic ability of a material to resist demagnetization. Its value is measured in oersteds and corresponds to zero intrinsic induction in the material after saturation. Permanent magnets with high intrinsic coercive force are referred as "hard" permanent magnets, which usually is associated with high temperature stability. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Features
   Continuous Duty Cycle       Duty cycle is the percentage of total on time over one complete on-off cycle within specific period. For small electromagnets, the specific time period is about 30 minutes for safety.  Continuous duty cycle refers to a magnet that can run continuously over this time period.
