what is coercivity

Asked by vishal mishra | 27th Dec, 2012, 05:34: PM

Expert Answer:

Coercivity measures how “permanent” a magnet is. It determines how much field is needed to “demagnetize” the magnet. High quality permanent magnets have high coercivity which makes them difficult to demagnetize.
