Detailed Solution

The given statement is false.
Concept: A piece of iron held close to an electromagnet will either be drawn to it or drawn away from it, or it may even have no effect. The ability of an electromagnet to produce such a field and the existence of any field of force that may interact with the iron piece will decide this. We'll strive toward these goals before attempting to respond to our inquiry.
It has been discovered that a conducting wire produces a magnetic field when a current is carried through it. The conductor wire is referred to as an electromagnet and this characteristic of conducting metal wires is known as electromagnetism.
An electromagnet is a transient magnet that can only function as a magnet while a current is flowing through it. The current flowing through it immediately affects the strength and range of this magnetic field; the bigger the current, the stronger the magnetic field, and vice versa.
Now, when stored in a magnetic field, iron is a material that exhibits evidence of attraction. In this instance, a magnetic field is also being produced by the electromagnet. Therefore, the iron piece will be drawn to the electromagnet.
As a result, the true statement is that an electromagnet can draw an iron piece.
Hence, the given statement is false.
