3. Write a short note on 'Care of Magnets'.

Answer:
Store your magnets with a keeper – A keeper is a small piece of iron that is generally added temporarily between the north and south poles of a magnet. It prevents the magnet from demagnetising by redirecting its magnetic field.
Store your magnets in pairs – Keep magnets in pairs to avoid both north and south sides from touching. Both poles of the same alignment should never be allowed to touch, as this will cause the magnetic fields to repel and cause the magnets to weaken over time.
A dry place – Corrosion easily occurs to magnets that are stored in a damp environment. Corrosion will affect the strength of the magnets, especially if they rust, which causes an air gap. This will produce an insecure bond for ferromagnetic materials. Also, if magnets get wet, it can cause the laminate to bubble. If a magnet must be used in wet environments, make sure you’re using a magnet designed for water, and that the magnet is dried and cleaned regularly.
Keep in a non-ferromagnetic space – When storing multiple magnets, keep them in a non-ferromagnetic container. A great example would be a tightened wooden box or Tupperware® container. The container your magnets are stored in will help the magnet avoid attracting any undesirable metal debris.
Help maintain the strength of your magnets
Many factors can play a role in the weakening of your magnets. Follow these simple tips to keep your magnets strong and useful:
Keep your magnets away from high temperatures. Speaking on an atomic level, having your magnets in a high-temperature area will allow the magnet’s chemical and physical properties to reach a level where they are no longer the same. This will cause them to lose their strength.
Try and keep your magnets separated from strong electrical currents. Strong electrical currents can cause your magnets to demagnetise by bothering the magnetic field.
Protect your magnets
Magnets will come with either casing or coating to protect them from corrosion or bumps. Generally, the coating will be rubber, which can be replaced if it becomes cracked or torn (which can sometimes occur after being exposed to the elements for an extended period).

Handling them with care is necessary to prevent personal injuries, property damages and magnet damages. Neodymium magnets are brittle; they can be broken or can splinter in a collision. ... Children should not be allowed to handle neodymium magnets as they can be dangerous.
