Pot Countersunk magnets are the most efficient design for gripping (other designs are preferable for lifting and attracting across air gaps).
1. Which is the strongest type of magnet?
Neodymium (more precisely Neodymium-Iron-Boron) Countersunk magnets are the strongest permanent magnets in the world.
2. Is one pole stronger than the other?
No, both poles are equally strong.
3. What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family.
Magnetic properties Neo Countersunk Rare Earth Magnet
Some important properties used to compare permanent magnets are:
which measures the strength of the magnetic field
the material’s resistance to becoming demagnetized
Energy product (BHmax)
the density of magnetic energy
Curie temperature (TC)
the temperature at which the material loses its magnetism
Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Special neodymium magnet alloys that include terbium and dysprosium have been developed that have higher Curie temperature, allowing them to tolerate higher temperatures.[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”] The table below compares the magnetic performance of neodymium magnets with other types of permanent magnets.[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
