The change in temperature was [ (37) - (-5) ] = 42 Fahrenheit degrees.
Kelvins and Celsius degrees are 9/5 (or 1.8) the size of Fahrenheit degrees.
42 F-degrees / 1.8 K per F-degree =<em> 23 and 1/3</em> Kelvins.
<u>Check,</u> using °C = (5/9) (°F - 32) and K = 273.15 + °C :
-5° F = -20.566° C = 252.594 K.
+37° F = 2.778° C = 275.928 K
(275.928K - 252.594K) = <u>23.334 K</u> close enough yay !
Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
