Magnetic Disc w/ Zn Plating Application:
These large discs are incredibly strong and are great for science and levitation experiments, but must be handled very carefully. They can pinch quite hard and will most likely break if two are allowed to slam together. Always use caution when working with magnets of this size.

Magnetic properties
Some important properties used to compare permanent magnets are:
Remanence (Br)
which measures the strength of the magnetic field
Coercivity (Hci)
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”][17] 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]
