Yes. The strength of the magnetic field surrounding a conductor is proportional to the magnitude of the current in the conductor.

How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
How do you produce electricity from electromagnetic waves?
Current flows through any conductor when electromagnetic waves fly past it. That's how a radio antenna works.
One important effect derived from electricity?
electromagnetic field around a conductor when ever current flows through it.
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
How does an antenna convert electromagnetic waves into a current?
According to Faraday's law: "When current is passed through a conductor, an EM field is produced surrounding it." As an antenna contains one or more conductors, the terminals of which are connected to some voltage, when this voltage at the terminals is applied, it produces/induces the alternating current which radiates the elements in the electromagnetic field. (Transmission) The reverse of this occurs in reception; where the electromagnetic field from another source induces an alternating current in the antenna, and a corresponding voltage at the antenna's terminals.
How does electromagnetic induction works?
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. Basically it works because of electricity.
What is needed for electromagnetic induction?
An electric current is produced by the change in Magnetic flux over timeRead more: How_do_electromagnets_work
Electromagnetic induction occurs in a coil when there is a change in?
Could you specify "coil"? Generally the electromagnetic induction occures due to variation of the B-field (magnetic flux density), variation of the current, I, or a change in the total area in which an electric current span over a B-field.
How much current flow through 3.5milimeter conductor?
how we decide current throuh conductor
What is the steady flow of electrons through a conductor?
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
What is the relation between current and thikness of conductor?
The thicker the conductor, the less the current that will flow through.
Does an electric current flow through a material that is conductor or an insulator?
A conductor
