An electric magnet (or as it is more usually called, an electromagnet) requires a core, composed of a piece of iron or any other ferro-magnetic metal, and a wire wrapped around the core, normally in many windings (for greater magnetic strength) all going in the same direction (e.g., clockwise). When a current flows through the wire, the metal core will produce a magnetic field.

How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
Is an electric bell a permanent magnet?
An electo-magnet is used in an electric bell.
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.
How do you make a self propelled magnet car?
I assume you mean an electric car. As an electric motor uses magnets or magnetism to rotate
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also?
strong
Does a magnet use an electric charge?
lol the term "magnet" means energy.
What is true about the magnet if an electric field exists around a magnet?
Then the magnet not only has magnetism, but also an electrical charge.
A magnetic field does not interact with a?
A) stationary electric charge B) moving electric charge C) stationary magnet D) a moving magnet
What makes the pickup guitar make sound?
A guitar pickup is wire coiled around a magnet. When the string vibrates, it causes the magnet to vibrate, which creates an electric current in the wire. The signal created by that electric current is then fed into the amplifier which converts it to sound.
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.
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
