Variable DC power supplies for electromagnets: switching or linear?
Hi,
I would like to build an electromagnet with parallel poles. I plan on buying a DC power supply. The magnets would be on for a while, not for short bursts.
The question is, should I buy a switching or linear power supply? I would most likely buy the Mastech brand.
I can't find any info about this online.
Thanks!
Buy whatever fits your power requirements and fits your budget. Either principle of operation, switching or linear, work great. That is why both are used.
