Any coil produces a magnetic field when it has an electic current passing through it.
It's usual to use copper wire, and 1 amp through ten turns has the same effect as ten amps through one turn . . etc.

If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.
Can a static magnet induce an emf in a stationary coil of wire?
No. In order to induce an EMF, the coil and the magnet must be moving in relation to each other.
Which of these forms of energy can be produced by passing the magnet through the coil of wire?
Electrical energy
How do electromagnet work?
If a wire is wrapped around a ferromagnetic material (those which are attracted by a magnet) and a current is flown through the wire, the material behaves like a magnet. This phenomenon is known as electromagnetism. The electromagnet can attract other ferromagnetic material just like any magnet. Usually a soft iron-core is used for good results. By such a phenomenon you get a temporary magnet whose magnetic property can be switched on or of by a switch! You can try this at home by wrapping a wire around an iron-nail and using a battery for current.Hope this helps:)
When a strong magnet is passed rapidly through a coil of wire what is true?
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
What wire coil acts like a magnet when a current flows through it?
Electromagnet
Why does an iron nail behaves like temporary magnet if insulated copper wire is wound around it?
which end of a magnet will pick up an iron nail?
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
When a magnet is moved through a coil of wire an electric current is generated in the coil because?
the magnetic field affecting the wire changes as the magnet moves.
What is soleniod?
A current-carrying coil of wire that acts like a magnet when a current passes through it.
What does solenoid do?
work as the current carrying coil-of wire on and acts like magnet when conductor flows
What do solenoids do?
work as the current carrying coil-of wire on and acts like magnet when conductor flows
Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through
How can sound be changed into electric current?
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
Does the power of a magnet increase if it is rapped in a coil of wire and you add current to the coil?
Find out yourself.
