Question

Mark true if the statement is true and false if it is false
An electromagnet does not attract a piece of iron.
A. True
B. False

Answer 1

Hint: An electromagnet will also attract or repel or even have nil influence on a piece of iron placed in its surrounding area. This will be found by the fact that there is some field of force that can interact with the piece of iron and if an electromagnet can produce such a field.

Complete step by step solution:
We can observe that, when a current is passing through a conducting wire, the current which flows through the wire produces a magnetic field. This behavior of the conducting metal wire is called electromagnetism and the conducting wire is known as an electromagnet.
An electromagnet is a momentary magnet that can perform as a magnet only if a current is being passed through it. The power and range of this magnetic field are proportional to the current that passes through it, which is better the current, better the magnetic field, and vice versa.
Now, iron is a material that displays signs of attraction when placed in a magnetic field. In this circumstance, the electromagnet is also producing a magnetic field. Thus, the piece of iron will be attracted in the direction of the electromagnet. Hence, an electromagnet will be able to attract a piece of iron. Hence, the statement given to us is False.
Hence, Option B is correct.

Note:
An electromagnet has quite a lot of applications. Heavy-duty electromagnets are used in iron ore fields to carry the ore from one location to another. They are also used in scrapyards where old used metal materials which are generally made up of iron are transformed into smaller chunks for suitable disposal.
