I installed a rev counter for a Kubota diesel engine & fitted the magnet to the steel power steering pump pulley ( same size as the crank pulley, but MUCH easier access)  & it works fine. I glued the first one on, but the counter didn't work - dumbo didn't realise the pickup is pole sensitive  :bang:. Second one is just held by it's own magnetism & has been fine for the last 18 mths (isn't it amazing how these temporary bodges become permanent?)

I have one a cheap Chinese tacho on my lathe. It worked well for a couple of weeks then stopped. After trying various things, including getting a spare pickup from the eBay seller. I discovered that turning the magnet over fixed the problem  :Doh: About 4 months ago it died again (after 7 years) and I've not yet tried to fix it.

My magnet is also held in place by the power of thought  :D

Mount the magnet to, or in the cam gear. No need to make it spark twice as much as needed.
