What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
How is an electromagnet like a permanent magnet?
No an electromagNet is created via electricity, once the electricity stops so does the magnet it can be created using a current in a wire tightly wrapped around a iron or metal rod
How was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor.AnswerCurrent is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
Can you make electricity using a wire and a magnet?
An electric current is created when a magnet is spun rapidly inside a coil of wire. A turbine (usually powered by water or wind) spins a magnet inside a coil. This action induces an electric current in the coil that can be used to power a light bulb. Hope This Helped!! :D

What is the key using a magnet and a conductor to induce a current in the conductor?
A changing magnetic field, in the conductor, can induce a voltage (and, under the correct conditions, that in turn will result in a current). In the case of a permanent magnet, either the magnet or the conductor has to move.
Can we make magnet without using magnetic material?
Yes. Electromagnets don't require a magnetic material; they just require a conductor and an electric 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 can electricity produce by using magnet?
Electricity is generated when a piece of conductive metal (such as copper) is passed through a magnetic field (or if the magnetic field is moved around the metal). A generator will have a copper wire in the center, surrounded by a magnet shaped like a torus (donut shaped, wire is in the hole in the middle). The wire is stationary. Electricity is generated when the magnet is spun (moving the magnetic field around the wire). This will generate an AC current (alternating current).
Why must you make a magnet by using batteries?
because battery supplies a direct current and to make a magnet with using the electrical method you need to supply direct current to the material {metal}which must be wounded with a coil {solenoid}.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
Can water be an electrical conductor using direct current?
Water can conduct current, but not as efficiently as a copper wire. There are some applications where a small current is used to sense the level of water through a conductor in an insulated container.
What is a magnet created using electric current?
An electromagnet. Unlike other magnets it can be switched on and off.
How you will get resedual magnatism?
If the question is "How do you create residual magnetism", one simple answer is as follows... You can "induce" a magnet in ferrous (containing iron) material using another magnet. Take the item you wish to make into a magnet (can be done using a simple magnet and a nail, in home experiments). An old stereo speaker magnet is best as it is relatively easy to find and pretty strong. Rub the magnet evenly and repeatedly ONE WAY down the item you wish to be magnetized (like from the nail head towards the point), almost like you are sharpening a knife. The longer you do this, the better magnet you will create (based on the size and material in your item and the strength of the inducing magnet). Over time, this induction will dissipate and you will have to re-induce the item. A more efficient, and a tiny bit more difficult method is electromagnetic induction, in which you would use a battery and a copper coil wrapped around the nail to create a flow of electrons (current) through the nail resulting in simultaneous magnetism. You can find easy instructions on how to do this just about anywhere on the web. You can SEE this happening by using a magnet near an old TV set screen, the magnet will induce or change the flow of electricity and produce warped colors. Don't use the family TV set, though, the colors sometimes STAY messed up 8). Have fun experimenting 8)
Why should a technician avoid using magnetized tools when repairing a computer?
They can induce current which can damage internal computer components.
