What's the difference between demagnetize and magnetic?
Demagnetize
Definition:
(v. t.) To deprive of magnetic properties. See Magnetize.
(v. t.) To free from mesmeric influence; to demesmerize.
Example Sentences:

(6) None of these treatments had a marked effect on the pigeon's orientation or homing under sunny skies, but a few results obtained under overcast skies suggest that demagnetizing the birds may have increased the scatter of their vanishing bearings.
(7) An enhancement to Dixon's technique is described which can provide error-free decomposition of water and fat proton images even in the presence of off-resonance conditions which result from susceptibility differences, demagnetization, or shim errors.
Magnetic
Definition:
(a.) Alt. of Magnetical
(n.) A magnet.
(n.) Any metal, as iron, nickel, cobalt, etc., which may receive, by any means, the properties of the loadstone, and which then, when suspended, fixes itself in the direction of a magnetic meridian.
Example Sentences:
