Hi all
I'm not well versed in electromagnetics but I'm learning as I'm prototyping this product.
Essentially developing a C shaped, DC, electromagnet to hold down a steel door on the order of about 8 sq. inches, and to release it when power is pulled. My current steel core is getting magnetized so it's not releasing. I'm following the trail to soft magnetic materials and I think I've identified a couple candidate alloys, namely Permendur, Invar, products with about 50% iron, but I want to get your feedback.
Specs needed:
High strength (the door will impact the core itself
Very high flux density
Minimum residual magnetism
Lowest cost
Is there an alloy I haven't considered that might meet these goals?
Thanks much!
