Question

do you think an electromagnet can be used for separating plastic bags from a garbage heap? eplain

Answer 1

Electromagnets can only attract magnetic materials. Plastic bag is a non-magnetic material and will not be attracted by an electromagnet. Hence, an electromagnet cannot be used for separating plastic bags from a garbage heap.

Answer 2

Answer:

No electromagnet is similar to a regular magnet in that it can only attract iron or magnetic materials.  Plastic bags cannot be distinguished from a waste heap using electromagnets

Explanation:

• When a current is supplied through an electromagnet, it begins to operate as a permanent magnet.
• The strength of the magnetic field of an electromagnet can be adjusted by adjusting the amount of current that passes through it, unlike a permanent magnet.
• Reversing the flow of electric current can change the polarity of an electromagnet.
• When a current is conducted through a conductor, a magnetic field is formed, which is how an electromagnet works.
• In this approach, the coil also works like a magnet by inducing a magnetic field.
• No electromagnet is similar to a regular magnet in that it can only attract iron or magnetic materials.
• Because all plastics lack magnetic properties, an electromagnet cannot be used to identify plastic bags from waste.
• Plastic bags cannot be distinguished from a waste heap using electromagnets.
• Electromagnets can be used to differentiate between iron and other magnetically active materials, as well as some electronic debris, reducing waste in our landfills and making it easier to separate plastic bags from the garbage.
• So, while a magnet cannot directly attract plastic objects, electromagnets can be highly useful for rubbish collection.
