Because iron is always attracted to a magent, it will be pulled from the mixture. Aluminium will only be pulled by the magnet if certain conditions are met; as long as the metals aren't moving very quickly, a magnet has no effect on it and won't be pulled away.
The only coins that are attracted to magnets are coins containing iron or steel, or a very high proportion of nickel. This includes many common coated-steel coins, and Canadian all-nickel 5-cent coins from the 20th century.
Yes, iron is a ferromagnetic material, meaning it can be magnetized and exhibit magnetic properties. When iron is brought into contact with a magnetic field, its atoms align to create a magnetic field, allowing it to be attracted to magnets and exhibit magnetic behavior.
Yes.
Rusty magnets can still attract and repel other magnets like regular magnets. The presence of rust on the surface does not significantly affect the magnetic properties of the magnet itself. However, excessive rust or corrosion may weaken the overall strength of the magnet.
No, bulbs do not make use of magnets to work. Light bulbs function by passing electricity through a filament, which then emits light and heat. Magnets are not involved in the process of generating light in bulbs.
The cans are made from aluminium.
A magnet would work fine, since aluminium isn't magnetic but iron is.
Natural magnets, such as lodestones, have a permanent and persistence magnetic field. These permanent magnets can also temporarily magnetize material such as iron, nickel, and cobalt.
The only coins that are attracted to magnets are coins containing iron or steel, or a very high proportion of nickel. This includes many common coated-steel coins, and Canadian all-nickel 5-cent coins from the 20th century.
Industrial strength magnets are used widely for lifting, work holders,and chucks.
Brass and copper are not magnetic materials, so a magnet will not pick them up. Magnets only attract materials that contain iron, nickel, or cobalt. To separate brass and copper from other materials, you would need to use methods such as sorting or using a different property like density.
Magnets can work through materials like plastic, glass, and wood. However, they are less effective through materials like aluminum, copper, and lead. They work best through materials like iron, nickel, and cobalt.
Sorting machines work by using sensors to detect different properties of items, such as size, shape, color, or weight. Once the items are scanned, the machine uses a system of belts, chutes, or air jets to separate the items into different categories based on the identified properties. This process allows for efficient sorting of items at high speeds.

Because you know how magnets work.
Magnets cannot attract or repel water because it is not a magnetic material. Wood and plastic also do not contain magnetic properties, so magnets will not affect them in the same way they would with metals like iron or steel.
