The Magnacore System, or the Magne System (マグネシステム Magune Shisutemu) is the third Beyblade System to be implemented, starting from December 2001. It is known as the NEO Spin Gear System (NEOスピンギアシステム NEO Supin Gia Shisutemu). It succeeded the Spin Gear System and has been succeeded by the Engine Gear System.
Also referred to as the MG System. The Magnecore System is compatible with some Spin Gear System Beyblades and Spin Gears can be exchanged with Magnecores. However, Spin Gears with the gimmick function cannot be switched out for Magnecores. On the other hand, Magnecores in some Magnacore System Beyblades cannot be switched out for Spin Gears. This is dependent on the Blade Base being used.
Known as the Five-Layer Structure, Magnacore System Beyblades consist of five basic parts (though with the inclusion Support Parts, it becomes a Six-Layer Structure):
A Bit-Chip (ビットチップ Bitto Chippu) is a circular part held in place by the Attack Ring. While Bit Chips were optional for the most part, it would usually come with decals that could be placed on it of it for aesthetic purposes. These stickers would usually portray a Bit-Beast from the Anime. Since Bit-Chips were short in length in their early stages, old Chips will not fit without Bit-Chip Covers.
Bit-Chip Covers (ビットチップカバー Bitto Chippu Kabā) were initially attached to all Beyblades released under the Inital System (First Generation) and their purpose was to protect Bit-Chips from damage. However, as Bit-Chip Covers would frequently fall out in battle, Bit-Chips were lengthened during the implementation of the Spin Gear System. Bit-Chip Covers became obsolete as they became difficult to disengage with the new Bit-Chips. In addition to this, old Beyblades with Bit-Chip Covers, such as Master Dranzer, have now been changed to include the longer Bit-Chips in Japan.
Attack Rings (AR)
Attack Rings (アタックリング Atakku Ringu) provide the Beyblade with it's main contact points and determine it's attack strength and effects. It is often the part that makes contact with opposing Beyblades first hence it's name. Attack Rings are decorated with various spikes and protrusions that accentuate its Type characteristics: Attack, Defense, Endurance etc.
A Sub-Attack Ring, or Secondary Attack Ring (二重アタックリング Nijū Atakkuringu) is compatible with Beyblades that do not have a fixed Attack Ring, such as Galeon Attacker. It is not compatible with Beyblades like Dragoon F, which has a fixed Attacked Ring. It can also be attached to Gabriel's Blade Base. Since it is not fixed, it can spin freely and has the effect of absorbing blows and eluding opponents' attacks. Any part capable of fitting a Sub-Attack Ring cannot be used without one.
Weight Disks (WD)
Weight Disks (ウエイトディスク Ueito Disuku) determine the weight and stabilises a Beyblade. Those with a large diameter can be used for attacking.
Blade Bases (BB)
Blade Bases (ブレードベース Burēdo Bēsu) contain the axis of a Beyblade. This part roughly determines the overall Type, spin and movement of a Beyblade provides them with traction. Prior to the implementation of the Spin Gear System, the Blade Base and Spin Gear were one in the same and could only spin right. Some were directly connected to the axis.
Magnecores (マグネコア Magune Koa) are Magnetic Spin Gears, further divided into NEO South & NEO North Cores.
- NEO South Cores repel magnets in a BeyStadium, increasing attack strength and speed, as a Beyblade will move more irregularly and unpredictably.
- NEO North Cores attract magnets in a BeyStadium, drastically increasing defense power as it will become more difficult to push back a Beyblade. However, rotational force will decrease.
Metal Weight Cores
Metal Weight Cores (メタルウエイトコア Metaru Ueito Koa) are non-magnetic and only contain weight blocks. They are heavier than Spin Gears but other than that, they are no different from the original Spin Gears.
Support Parts (SP)
Support Parts (サポートパーツ Sapōto Pātsu ) can be customised onto Blade Bases that are compatible with Support Parts. It replaces the parts that make contact with opposing Beyblades' frames. It is only equipped on later Magnacore System Beyblades and Random Booster 8's Ariel 2 (Atari 1). Though what is attached to Gabriel’s Blade Base has the same purpose, it is different from Support Parts.
Custom Magnets can be purchased and used in specialised BeyStadiums, changing a Beyblade's movement patterns. These BeyStadiums were designed to always have the South Pole of magnets facing upwards.
For Takara versions, only a certain selection of beyblades have magnetic cores which would otherwise need to be purchased separately. Hasbro usually added magnetic cores to beyblades which Takara did not release with a magnetic core.
