Question

A heap of metal scrap in a factory contains objects made of copper, aluminium, iron, zinc, steel, nickel, cobalt and lead. Which of these can be removed by using a magnet?

Answer 1

Scrap consists of recyclable materials left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling

Answer 2

Magnet

Explanation:

• Magnet is a material or object used to attract metals with the help of magnetic field.
• This magnetic field of the magnet is invisible but it is majorly responsible for the most recordable property of a magnet.
• A force which pulls on different ferromagnetic materials is called magnetic force.
• A ferromagnetic materials are iron, steel, zinc, nickel, cobalt, etc. and attracts or repels other magnets.
• Only aluminium and lead are the two elements which can not attracted from the magnet.
• Hence, aluminium and lead cannot be attracted with the help of magnet, as all other metals would get attracted to it.
