SUMMARY

This discussion focuses on the construction of AC electromagnets, highlighting the advantages of AC over DC electromagnets in terms of frequency response. Key recommendations include using a soft iron core and increasing the number of coil turns and current to enhance magnetic strength. Experts advise caution when connecting directly to mains power and suggest using a low resistance high power resistor to prevent short circuits. Additionally, the use of a horseshoe-shaped core is proposed for creating distinct north and south poles.

PREREQUISITES
  • Understanding of AC electromagnet principles
  • Knowledge of soft iron core materials
  • Familiarity with coil winding techniques
  • Basic electrical safety practices

I'm trying to make an AC electromagnet (better frequency response compared to DC electromagnets) I could not find any document, book, or source to check if I'm on the right way or not. I have a coil and a core and working on them to increase magnetic field, right now it is not high enough. Anyone having experience?
Thanks a lot
Mike

More turns and higher current make it stronger. The core needs to be soft iron for best results. If you get a nice long think wire wrapped round a core and plug it into the mains it works very well, however its dangerous! and I wouldn't advise it. (If you use a low resistance high power resistor in the circuit you won't short out your supply.)
Also you could get a horce shoe shaed core and wrap the wire round one side and then in the opposite direction on the other side to make a N and S pole.
 
What what purpose? How can a 'DC' electromagnet have a frequency response??

There are lots of magnetic materials for a variety of uses up into the microwave region.. Ferrites and powdered iron.
