which will produce a magnetic field?\nany wire with or without a current\na wire formed into a coil\na wire carrying a current\na wire formed into a single loop
Answer
Brief Explanation:
According to the principle of electromagnetism, a magnetic - field is produced by an electric current. A wire without a current does not produce a magnetic field. A wire formed into a coil or single - loop only produces a magnetic field when there is a current flowing through it. A wire carrying a current will always produce a magnetic field around it.
Answer:
a wire carrying a current
