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.
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 do you make electricity using only a magnet?
A moving magnet will cause an electric field - a voltage. This can cause currents in nearby conductors.
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. . .
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.
Electric waves and magnetic waves move in directions that are?
Electric and Magnetic currents travel from Positive to Negative. a batteries charge travels from the + end to the - end. and a Magnet travels from North to South.
Which magnet made by an electric current flowing through wires?
Electromagnet.
What role do electrons play in magnetism?
Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).Magnetism is produced through electric currents.

Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.
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.
