What type of magnet can only attract materials when it is touching another magnet?
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.
When adding more paper to a magnet on refrigerator why does it cause the magnet to fall off?
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.
Is a strong magnet that can be turned on and off?
an electromagnet
Is not a permanent magnet?
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.
How can you make magnet using stroke method?
To make a magnet using the stroke method, take a ferromagnetic material, such as iron or steel, and stroke it with a strong magnet in one direction. Ensure that you consistently move the magnet in the same direction and lift it off the material each time instead of rubbing back and forth. This process aligns the magnetic domains within the material, effectively magnetizing it. After several strokes, the material will exhibit magnetic properties.
What magnet can be switched on and off?
An electro-magnet can be turned on and off.
How can you make a magnet stick to aluminum?
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.

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.
What is a magnet that can be turned off?
An electromagnet.
Can you make a stronger magnet using a weak magnet?
yes
How do you make an iron a magnet?
by stroking it with another magnet :D
How do you make a science models with magnet?
put a stick with a magnet

Where you get magnet?
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.
How does a magnet with an on-off switch work?
A magnet with an on-off switch works by controlling the flow of electricity to the magnet. When the switch is turned on, electricity flows through the magnet, creating a magnetic field. This magnetic field attracts or repels other magnetic objects. When the switch is turned off, the flow of electricity stops, and the magnetic field disappears, causing the magnet to no longer attract or repel objects.
Is a strong magnet that can be turned on and off?
an electromagnet
