The work done is the loss of kinetic energy.
Loss of kinetic energy = m*(v1^2 - v2^2)/2 = 10 kg * [ (99m/s)^2 - (1m/s)^2]/2 = 49,000 J
NATURAL MAGNETS
A natural magnet is one that occurs naturally in nature. All natural magnet are permanent magnets , meaning they never lose their magnetic power.
Natural magnet can be found in Sandy deposits in various part of the earth .
The strongest natural magnetic material is LODESTONE also called magnetite.

It's these magnets that is in our refrigerator doors, which have extra-stronge magnetic power. There are two types of of artificial magnets. Temporary and Permanent Magnets.
Examples of artificial magnets are; electromagnet and the paper clip.
Examples of Permanent Magnets are; Alnico
