A Hornby replacement magnet can be the right size and still be the wrong spec.
For restoration work, fit is only part of the problem. The magnet also needs enough pull for reliable operation, the right hole position, and a grade that holds performance under heat.
This is why we stock a 12.7mm x 9.3mm x 13.2mm N42SH neodymium block magnet with a 2.5mm hole, rated to 150°C and 6.27kg pull.
Small part, Big difference.
