which will produce a magnetic field?\no any wire with or without a current\no a wire formed into a coil\no a wire carrying a current\no a wire formed into a single loop
Answer
Brief Explanations:
According to Ampere's law, a magnetic - field is produced by an electric current. A wire without a current does not produce a magnetic field. Just having a wire in a coil or single - loop shape does not produce a magnetic field without a current. A wire carrying a current will produce a magnetic field around it.
Answer:
a wire carrying a current
