which item produces the magnetic field in the electromagnet?
Answer
Answer:
The first - image (wires).
Explanation:
Step1: Recall electromagnet principle
An electromagnet's magnetic field is produced by electric current flowing through a coil of wire.
Step2: Identify relevant item
The first image shows wires which can carry current to create a magnetic field in an electromagnet. The second image is a permanent magnet (horseshoe magnet) and the third is a switch - they do not produce the magnetic field in an electromagnet.
