What are the best sixe and type of Chuff Magnets.
I am putting two on an axle and looking for good performance with a reed switch.
For example should I use N42 or N48 strength for best performance especially at speed.
Are bar magnets easier to use or should I use round ones.
Neodymium magnets are now pupular and have increased magnatism for a small space. Are these now a better choise for chuff applications?
