A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force. Steel is one such substance. (A magnetically soft substance can only be magnetised temporarily.)

Halite is hard. It can be scratched by a steel file and a knife with difficulty
How hard is a steel knife on Mohs hardness scale?
A typical steel knife would be in the 5-5.5 range on the Mohs scale.
What is the hardness of 55 -58 HRC mean?
Hardness of metal is determined by the carbon content. HRC is the Rockwell Hardness Scale. A hardness of 55-58 is not very hard compared to carbon steel.
Why won't a magnet pick up a penny?
because the penny can't be magnetically charged.
Is vitallium magnetic?
Vitallium is not magnetic. The main ferromagnetic metals are iron, nickel, and cobalt. These metals will be magnetically impacted at varying degrees depending on their participation in alloys. While the Vitallium alloy features a high cobalt content, it does not behave magnetically.

I thought 18 8 Stainless Steel was supposed to be non magnetic?
The "8" means 8% nickel. Than is a magnetically active material.
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
What memory has an magnetic hard drive to improve system performance?
If you are referring to RAM, none because it would slow it down. Hard drives and floppies are magnetically written to.

How do you magnetize steel bar?
a steel bar is a magnetically susceptable material. if you apply a magnetic field through the steel bar, such as applying a DC current through a solenoid winded around it, it will become magnetized. Just rubbing a magnet against the steel bar will help align all the magnetic dipoles in a general direction for it to be considered a magnet.
