Neodymium magnet 5x10x2 2 pcs

Two NSR neodymium magnets with the exact size you need

Neodymium magnets are one of those components that make a difference between a car that stays on the track and one that goes off at the first demanding corner. This pack of 2 NSR magnets measuring 5x10x2 mm provides the necessary magnetic force to maintain just the right downforce, without overdoing it or falling short, both on home circuits and at club meetings.

Main features

• Material: neodymium (NdFeB), the type of permanent magnet with the highest energy density available today.
• Dimensions: 5 x 10 x 2 mm — rectangular format with a slim profile, common in modern slot car chassis.
• Contents: 2 units per pack.
• Brand: NSR, reference NSR4870.

Function and performance

The neodymium magnet in a slot car acts on the metal rails of the circuit generating a vertical attraction force — the so-called magnetic downforce — which increases grip without adding mechanical weight to the assembly. The result is greater stability in corners and increased tolerance to driving errors, especially on circuits with fast corners or steep banking.

The 5x10x2 mm format is slim enough to fit into chassis slots where thicker magnets cannot be accommodated, and its 10 mm length provides a reasonable working surface to generate effective and uniform attraction.

Compatibility and installation

Being a standard rectangular neodymium magnet, it can be used in any slot car chassis that has a slot for magnets of these dimensions. Before installation, it is advisable to check the correct polarity: the side of the magnet facing the track should be the one that generates attraction. An inversion of polarity drastically reduces the effectiveness of the downforce.

Remember that the regulations of some club or federated championships regulate or limit the use of neodymium magnets. Always check the rules of your championship before preparing the car for competition.

Installation and preparation: common mistakes

• Inverted polarity: the magnet repels instead of attracting. Always check with a reference magnet before securing.
• Gluing without cleaning the slot: grease or dust residues reduce glue adhesion and may cause the magnet to shift with the heat of the track.
• Using more magnets than necessary: more magnetic downforce is not always better. An excess can slow down the car and increase wear on braids and rails.

Frequently asked questions

How many magnets are in the pack?

The pack contains 2 neodymium magnets measuring 5x10x2 mm.

Are they compatible with any circuit?

Neodymium magnets work on metal rails, present in the main circuit systems on the market: Scalextric, Ninco, Carrera, Scaleauto, Slot.it, etc. On plastic circuits without conductive rail, they have no downforce effect.

What adhesive is recommended for securing them to the chassis?

Medium viscosity cyanoacrylate or two-component epoxy is commonly used, depending on the chassis material. Clean the slot well before gluing to ensure good adhesion.

Can I use them in competition?

It depends on the regulations of your championship. Some club or federated regulations limit the type, size, or number of magnets allowed. Always check the rules before preparing the car.

Is the polarity marked on the magnet?

Neodymium magnets usually do not have visible polarity markings. Check it by bringing the magnet close to a reference one or directly to the rail of the circuit to identify which side attracts before gluing it.
