Write the names of the materials used to make permanent magnets.
(N/A) Permanent magnets are typically made from materials that have high retentivity and high coercivity,allowing them to retain their magnetic properties even after the external magnetizing field is removed. Common materials include:
$1$. Steel
$2$. Alnico (an alloy of iron,aluminum,nickel,and cobalt)
$3$. Cobalt steel
$4$. Ticonal (an alloy of iron,nickel,cobalt,titanium,and aluminum)
