a radio needs a magnet because then it would not tell you things that are happening around the place. There arealso many other things that need magnets such as a video tape, television, cabinet drawer, computer, etc.
Objects that contain iron, nickel, or cobalt are attracted to a magnet.
Iron has a very high permeability. So it lets maximum number of Magnetic lines of force to pass through it. The closer is the ironic conductor to the magnet, more is the number of lines of force passing through the ironic object. That is why the magnet attracts the ironic object.
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
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.
A magnet works by creating a magnetic field around itself. This field attracts objects made of certain materials, like iron and steel, while repelling objects with their own magnetic field. This attraction and repulsion are caused by the alignment of the magnetic domains within the material, which either align with or oppose the magnet's field.
You can attract objects that contain iron by using a magnet, as iron is a magnetic material. When you bring a magnet near objects containing iron, the magnetic force will cause them to be attracted to the magnet.
Objects or materials that are attracted to a magnet are typically made of iron, nickel, or cobalt. These materials have magnetic properties that allow them to be attracted to a magnet.
the magnet attracts to iron by the magnetic field both the iron and the magnet have
In order to have a magnetic interaction u need 2 objects... do the experiment..1. Get 2 magnets/ buy 2 magnets2. Put them close together and they will have a strong interaction...THATS THE PROOF...
A magnet has a magnetic field around it. The magnetic field causes a magnetic force that can attract objects to the magnet.
Try tapping the magnet lightly to dislodge any debris or objects that may be causing it to stick. If that doesn't work, heat the magnet slightly using a hair dryer to weaken the magnetic force temporarily. Avoid using excessive force to prevent damaging the magnet.
A fridge magnet works by creating a magnetic field that attracts to the metal surface of a refrigerator. The magnet is typically made of a material, such as iron or a ferromagnetic alloy, that retains its magnetic properties. This allows the magnet to stick to the fridge and hold papers or other lightweight objects in place.
