What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
What does a changing electric field induce?
A changing electric induces changing electric fields:The law of Electromagnetism is Invariance of the Electromagnetic field. The vector or induction portion is "o = dEv/dr + Del Er + DelxEv = dEv/cdt + Del Er + Del x Evthis is the same law as Faraday's law but it includes the Gradient Del Er0= dBv/dt + Del Er + Del xEv
Does a coil carrying electric current create a magnetic field?
No, The magnet rotates/moves through the coil, inducing a current into the coil by disturbing the coils magnetic field. A transformer works the exact same way.
Can a magnet create electricity?
yes, when a copper wire is coiled around it and attached to a battery, an electrical current passes through it. =============================== The above is not the apt answer for the query made. Yes when a magnet is moved through a coil of wire then current is induced in it. This phenomenon is known as electro magnetic induction and current is known as induced current. This is because of change of magnetic flux linked with the coil. So whenever there is a change in magnetic flux linked with a closed circuit then current is induced in the circuit. The current lasts so long as there is change in magnetic flux. Just link of magnetic flux will not induce any current. Only the change of magnetic flux does everything. This is very very important.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Where do electric generators direct the current they induce?
An electric generator generates the current by moving a coil of wire through a magnetic field. This is normally in the inner mechanisms of the device.
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
Can magnets produce electric currents?
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
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.
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
What does a changing magnetic field induce?
An electrical current.
Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
What is a magnetic created when electric current flows through a coil of wire?
Nothing is ever created, however, Electricity is INDUCED. The process is interchangeable, so if you pass a current through the wire you have a magnetic field (electromagnetism)lol.-originalposter- When you pass a magnet through a coil of wire, you induce an electric current. Also, if you move the coil instead you get the same result.-norman
