when current flows through a wrapped in coils around a bar magnet, a temporary magnet known as a _________________ is created.
Did you omit a word? perpahs metal. For the blank, are you thinking of electromagnet?
Yes, you are correct! The word I omitted in the statement is "coil." So, when current flows through a coil wrapped around a bar magnet, a temporary magnet known as an "electromagnet" is created.
To explain how to arrive at this answer, let's break it down:
1. The question states that current flows through a "wrapped in coils" around a bar magnet. This indicates that an electric current is passing through a coil of wire wound around a bar magnet.
2. When an electric current passes through a coil of wire, it generates a magnetic field around the coil. This is due to the interaction between the electric current and the metal wire.
3. Now, since the coil is wrapped around a bar magnet, the magnetic field generated by the electric current interacts with the existing magnetic field of the bar magnet.
4. As a result of this interaction, the combined magnetic field creates a temporary magnet, known as an "electromagnet." The strength of the electromagnet's magnetic field can be controlled by adjusting the amount of current passing through the wire or by changing the number of turns in the coil.
So, to summarize, when current flows through a coil wrapped around a bar magnet, a temporary magnet called an "electromagnet" is created.
