5 mm neodymium magnet

The magnet that makes a difference in every corner

The NSR4828 neodymium magnet is one of those components that go unnoticed until you need them. With a diameter of just 5 mm, this small neodymium magnet works silently within the chassis, providing the magnetic grip that allows the car to stay glued to the track in the most challenging corners.

NSR includes it in a 2 units pack, designed to always have a spare on hand or to equip the two anchoring points of your chassis when the design requires it.

Main features

• Material: neodymium, known for its high magnetic energy density in a very small volume.
• Diameter: 5 mm.
• Content: 2 units per pack.
• Reference: NSR4828.
• Manufacturer: NSR.

Function and performance

In slot cars, the grip magnet serves a critical function: it generates magnetic attraction to the metal track, reducing the risk of derailment in fast corners and during sudden braking. Neodymium magnets offer considerable strength for their size, making them the usual choice in competition chassis where space is limited.

The choice of the right magnet—both in shape and intensity—directly influences the balance between grip and freedom of movement of the chassis. A magnet that is too powerful can weigh the car down on the straight; one that is too weak compromises stability in corners. The NSR4828 is sized to fit the standard magnet positions of NSR chassis and provides a solid starting point for adjustment based on track type and driving preferences.

Compatibility and installation

This magnet is designed within the NSR spare parts ecosystem, a brand known for its extensive catalogue of interchangeable components. Before installing it, check that your chassis housing accommodates 5 mm diameter magnets and that the polarity is correctly oriented towards the track.

If you have questions about which magnet is most suitable for your chassis and track combination, our team at Ministry of Hobby can guide you without obligation.

Ideal for…

• Drivers looking to replace worn or lost magnets in their NSR chassis.
• Enthusiasts wanting to experiment with different levels of magnetic grip on the track.
• Preparers tuning cars for club competition who need to keep controlled spares.

Frequently asked questions

What is the difference between a neodymium magnet and a ferrite one?

Neodymium generates a magnetic force far superior to ferrite for the same size. This allows the use of smaller magnets without sacrificing grip, which is especially useful in compact chassis where space is limited.

Does this pack include 2 magnets or is it just 1?

The NSR4828 pack includes 2 units of 5 mm neodymium magnets.

How do I know if my chassis accepts 5 mm magnets?

Check the manual or technical sheet of your NSR chassis. In many models, the magnet housing is specified with the accepted diameter. If in doubt, measure it with calipers before placing the order.

Does the orientation of the magnet affect performance?

Yes. The polarity must be correctly oriented so that the attracting face is facing the metal track. An inverted installation would reduce or nullify the grip effect.

Can I use these magnets in chassis from other brands?

As long as the housing accommodates a 5 mm diameter magnet, it is possible. However, check the exact dimensions (diameter and height) before attempting installation to avoid forced adjustments.

The NSR4828 is a pack of 2 neodymium magnets measuring 5 mm in diameter, designed for slot car chassis that require precise magnetic downforce. Neodymium magnets deliver high magnetic strength in a compact format, making them a go-to choice for competitive slot racing setups. Compatible with NSR chassis systems and suitable for 1/32 scale slot cars, these replacement magnets help maintain consistent grip on both Scalextric and Ninco universal rail tracks as well as Scaleauto and Slot.it sport rail tracks.
