What magnet is made by electric currents?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
How can the use of electric currents be employed to create a magnet?
Electric currents can create a magnet by running through a coil of wire, which generates a magnetic field. This process is known as electromagnetism.
What is A tempoary magnet made when electric currents flows through a wire wrapped around an iron case?
This is called an elecro-magnet, and it is only magnetized while current is running through it.
How does the interaction of magnetic fields and electric currents contribute to what makes a magnet work?
The interaction of magnetic fields and electric currents creates a magnetic force that aligns the atoms in a material, making it magnetic. This alignment allows the material to attract or repel other magnets, which is what makes a magnet work.
Are permanent magnets produced by electric currents?
No, permanent magnets are not produced by electric currents. They are made from materials that are magnetized and retain their magnetic properties without the need for external electric currents.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
Do permanent magnets produce electric currents?
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.
What is true about electric currents and magnets?
Sort of... In permanent magnets, magnetism is due to the movement of electrons around their atoms. Each atom is a small magnet, and there are more atoms aligned in one direction than in the other. If you consider the electron orbiting around the atom, or "spinning around its axis" as a "current", then yes.
What is a magnet made by electric current?
An electromagnet.
What kind of magnet is a magnet made from a steel paper clip?
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
Does adding electric currents to something that is already magnetized increase or decrease the power of the magnet?
By 'adding electric currents', you are presumably talking about passing a d.c. current through a coil wound around a magnet?First of all, you cannot increase the flux density of a magnet beyond saturation, regardless of the current or number of turns that make up the coil. Whether on not you increase or reduce the flux density depends on the polarity of the coil compared with the polarity of the magnet; if they are opposite then, yes, you can demagnetise the magnet and, in fact, remagnetise it in the opposite direction.
Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.
