A temporary magnet, such as an electromagnet, can only attract materials when in contact with another magnet or when an electric current is flowing through it. It loses its magnetism when the current is turned off or the magnetic field is removed.
Adding more paper increases the distance between the magnet and the metal surface of the refrigerator. The farther the magnet is from the metal, the weaker the magnetic force holding it in place. This reduced magnetic force can cause the magnet to fall off.

An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
To turn off the magnet in the mission, you can either deactivate the power source that is supplying it or physically remove the magnet itself. It is important to follow safety protocols and instructions to ensure proper procedure is followed when dealing with magnets.
An electro-magnet can be turned on and off.
You cannot make a magnet stick directly to aluminum because aluminum is not magnetic. However, you can make a magnet stick to aluminum by placing a magnetic material, such as iron, in between the magnet and the aluminum surface.

yes
put a stick with a magnet
by stroking it with another magnet :D
To get a magnet.Magnets are available in nature.You can make a magnet by tying a piece of iron to a strong magnet for some time.You can also get a magnet by making an Electo-magnet or solenoid.

You can magnetize a piece of steel or iron, by stroking it with one end of a magnet. Stroke in one direction only, lifting off and away between each stroke. This aligns the atoms in a regular direction, in the blank piece of steel.
