Thanks for the reply Mike.
My apologies, the final coil dimensions are:
1.25" Diameter x 1.875 Length
The airgap is 1/8" and the armature is 1.5"x1.5"
The inductance is 6.625 mH
The power draw as read by meter:
5V @ 2A = 10W (with a fresh 9V battery)
994T x 2A = 1988 AT
Wire gauges of #30...
Core permeability and electromagnet design
How much of a benefit might a higher permeability core provide and how might I improve on my electromagnet design?
I have been working on a design that uses a DC electromagnet to actuate a small armature over a small airgap.
My resources have been...
