How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
What does electric current produce?
A electric current produces a magnetic field
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
What happens when there is a change in the magnetic field in a closed loop of wire?
It produces a current.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
How could straight copper wire produce magnetic field lines?
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?

An electric current produces a magnetic field?
Yes.
What does electric current produce?
A electric current produces a magnetic field
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
What does moving electricale charge produce?
It produces a magnetic field.
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
What is a coil of wire that when carrying a electric current produces a magnetic field?
No field
What does a moving magnectic field produce?
A moving magnetic field produces current
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
